What changed and why

A password in --osv-url was printed as is in the advisory source line, the batch and detail errors, and the debug log.

  • --osv-url with a username or password is now refused up front: --osv-url must not include a username or password. Remove them from the URL. fetch can't use them anyway.
  • Two things run before that check, so they mask it themselves: the CLI started debug log (argv) and the Invalid value for --osv-url error. Both use redactArgCredentials: if the value parses, new URL clears the username and password, and if it doesn't parse and has an @ it's shown as <hidden>, since there's no safe way to find the password in a broken URL.
  • redactUrlCredentials masks URLs inside longer text (source label, both OSV errors, debug log urls), so it shows https://***@127.0.0.1:9 if one ever slips through. It stops at spaces so it doesn't eat normal text.

JSON, HTML and SARIF never had the URL, and SBOM already writes null for a custom endpoint.

Tests: new cases in tests/validate-url.test.ts, tests/validate.test.ts, tests/advisory/osv-advisory-source.test.ts and tests/e2e/debug-bundle.test.ts for the refusal, the source line, both OSV errors, the debug log and the invalid URL message. Each one fails if I break the code it checks. Also ran the CLI with --debug and a few bad --osv-url values (space, leading space, / in the password, https:/, both --osv-url x and --osv-url=x) and the password didn't show in the terminal, the debug log or the debug bundle.

Closes #1642

Refuse --osv-url with a username or password, and mask user:pass as ***
wherever the endpoint is printed.

Closes OWASP#1642

Summary

Summary by CodeRabbit

  • Security
    • OSV URLs containing a username or password are rejected.
    • Credentials are masked in OSV error messages, source labels, debug logs, and logged command-line arguments.
    • Invalid OSV URL messages hide embedded credentials, including in malformed inputs.
    • Requests continue to use the configured URL; only displayed or logged information is redacted.
  • Tests
    • Added coverage for URL rejection and credential masking in messages, labels, and logs.

OSV URL validation now rejects URLs that contain credentials. Selected OSV logs, labels, errors, and debug arguments redact credentials. Redaction does not change the URL used for requests.

Changes: OSV URL credential protection

Full details: Title check

Explanation

The title follows the required "type: short description" form with the allowed type "fix", lowercase after the colon, and no trailing period. It names the main change: credentials in --osv-url output are hidden. The scope "(osv)" is an extra element that the format does not forbid.

Full details: Description check

Explanation

The description follows the template's "What changed and why" section and includes a "Closes #1642" line. It explains the change in detail, lists the tests added, and describes manual verification. The template has only one required section, and the description fills it.

Full details: Linked Issues check

Explanation

I checked the requirements of [#1642] against the head code in src/utils/validate-url.ts and src/scanner.ts. I used the whole-PR summary for the other hunks.

Up-front refusal (ideal item): validateOsvUrl throws --osv-url must not include a username or password. Remove them from the URL. when parsed.username or parsed.password is set. This check runs after the HTTPS check and before the DNS lookup.

Source line (done-when item 1): createAdvisorySource in src/scanner.ts builds the label with redactUrlCredentials(options.osvUrl). For the issue URL, the label shows https://***@127.0.0.1:9.

Batch and detail errors and debug output: the summary states that OsvAdvisorySource.queryBatch and getVuln redact URLs and error text in the debug entries and in the rethrown errors. Fetch still uses the original URL. I did not read that hunk directly.

Argv and invalid-value output: redactArgCredentials at head handles whole URLs and --flag=value arguments. It masks parseable credentials and replaces an unparseable value that contains @ with &lt;hidden&gt;. The summary states that src/index.ts applies it to the CLI started debug log and that src/cli/validate.ts applies it to the invalid --osv-url message. I did not read those hunks directly.

Tests (done-when item 2 and completion criteria): the summary lists new cases in tests/validate-url.test.ts, tests/validate.test.ts, tests/advisory/osv-advisory-source.test.ts, and tests/e2e/debug-bundle.test.ts. I did not run them.

Residual limit: redactUrlCredentials matches [^\s/?#]+@. A raw /, ?, or # inside a password in free text can leave part of the password visible. Such a URL is not valid, and the refusal blocks it from the endpoint setting.

Full details: Out of Scope Changes check

Explanation

Every changed area relates to [#1642]. redactUrlCredentials and redactArgCredentials change only the text that is printed, logged, or thrown. The validateOsvUrl refusal implements the issue's ideal requirement. The source label, OSV error and debug changes, the argv and invalid-value redaction, and the tests all belong to the same credential-redaction work. The summary shows no unrelated feature or refactoring work. Fetch still uses the original URL, so request behavior does not change. I did not read the src/index.ts, src/cli/validate.ts, and src/advisory/osv-advisory-source.ts hunks directly. This conclusion relies on the summary for them.

Full details: Linked Issue

Explanation

I checked the PR description for an issue reference. It ends with "Closes #1642", which uses the Closes keyword followed by an issue number. The linked issue is #1642, "--osv-url prints a password in the URL in plain text," and the PR body matches it. The check passes on this reference alone. I did not need repository tools because the check only tests the PR body text.

Full details: Closes Keyword Matches Scope

Explanation

The PR body uses Closes #1642, so I checked issue #1642 against the diff. Issue #1642 asks for three things: 1. Redact the OSV endpoint everywhere it prints. The issue names the advisory source line, the batch and detail errors, and "any other output" such as JSON, HTML, SARIF, or the debug log. The diff covers this: - src/scanner.ts wraps the source label with redactUrlCredentials. The terminal line in src/scan/single-scan.ts prints this label. - src/advisory/osv-advisory-source.ts redacts the batch error, the vuln-detail error, and the URLs and error payloads in the debug log. - The debug bundle already redacts URLs and private keys such as osvUrl in src/utils/debug-redaction.ts. The PR does not change that file. - I searched src/output/scan-json.ts, sarif.ts, html-reporter.ts and the other reporters. None of them references osvUrl, sourceLabel, or advisorySourceLine. So the endpoint never reaches JSON, HTML, or SARIF, as the PR description says. - The CLI started debug log now redacts argv. The invalid --osv-url message uses redactArgCredentials. - One raw osvUrl value remains in a debug call in single-scan.ts. It runs after validateOptions has refused any credential-bearing URL, so the CLI does not reach it with credentials. 2. Refuse credential-bearing URLs up front (listed as "ideally"). validateOsvUrl in src/utils/validate-url.ts now throws --osv-url must not include a username or password. Remove them from the URL. This matches the issue's suggested wording. 3. Tests for terminal redaction and the error path. The PR adds tests in tests/advisory/osv-advisory-source.test.ts for the source label, batch error, detail error, and debug URL. It adds tests in tests/validate-url.test.ts and tests/validate.test.ts for refusal and for the &lt;hidden&gt; invalid-URL message. It adds an e2e debug-bundle test in tests/e2e/debug-bundle.test.ts. Every required item is delivered, and the optional refusal is delivered too. Nothing is missing, so the Closes keyword does not auto-close the issue with work still unbuilt. The PR author is Medhansh-741 (provider-reported).

Full details: No New Runtime Dependency

Explanation

Hey, this one is simple. The PR does not touch package.json. The changed-file list for base..head has nine files, all under src/ or tests/. No lock file changed either. I also compared package.json at the base and head refs. Both have the same five runtime dependencies: better-sqlite3, fflate, semver, yaml, and yarn-lockfile. Neither has optionalDependencies. The devDependencies count is 9 in both. So no new runtime entry was added, and no package moved from devDependencies into dependencies. The check passes. The PR adds no runtime package. The redaction code uses the existing URL API and the existing helpers in src/utils/validate-url.ts.

Type the { all: true } mock callbacks for an address array.

This PR changes tests/validate-url.test.ts, and the test type-check gate fails on any error in a changed test file. Lines 227 and 252 pass [] to a callback typed (err, address: string, family: number) => void. TypeScript reports TS2345 because never[] is not assignable to string.

The { all: true } branch returns an address array, so the single-address callback type is wrong for that branch. Give that branch a callback type that takes an Array<{ address: string; family: number }> result. Do not cast the argument or widen the callback type to make the error go away. The success branches at lines 225 and 250 use as any for the same mismatch, and a correctly typed callback can remove those casts as well.

This is a clean, small fix and it covers most of #1642: the source label, both thrown error messages, the invalid-URL echo, the argv debug log, and it refuses credentials up front in validateOsvUrl so nothing is fetched with them.

One gap, and it is in a place the issue names explicitly ("the debug log"):

// batch, src/advisory/osv-advisory-source.ts
this.debugLog("OSV request failed", {
  ...
  error: error instanceof Error
    ? { message: error.message, stack: error.stack }   // <- unredacted
    : String(error),
});

Same shape in the getVuln failure branch. Any underlying error whose message embeds the endpoint — TypeError: Failed to parse URL from https://user:secret@…, or a wrapper that includes the request URL — reaches --debug intact. The thrown message is redacted, so the terminal output is safe; only the debug payload leaks. redactUrlCredentials already works on arbitrary text, so wrapping error.message (and stack if present) is a one-line change in both branches.

Second, smaller point: redactUrlCredentials only matches with a scheme. If a message ever carries user:secret@host without https://, it is not caught. Tightening the authority match would cover that, though it is more likely to over-match ordinary text, so this one is your call.

Everything else reads correctly, including applying the redaction before the Invalid value for --osv-url interpolation — that path would otherwise print the whole credential-bearing string.

Mask user:password in the error message and stack that the batch and
getVuln failure branches send to the debug log. Also let the redaction
regex match userinfo that contains a space, so the CLI started log
does not keep a password like "my password" in clear text.

@Skeletor-Pirate Good catch, thanks. Both failure branches now run error.message and error.stack through redactUrlCredentials, and the debug log test checks the whole payload now, not just the url field. It failed before the change.

I left the schemeless user:secret@host case alone for now. Like you said it would start eating normal text, and the only places that pass the endpoint around always have the scheme on it.

Thanks @Medhansh-741, this is a good first PR. Refusing the URL up front is the right call, since fetch can't use the credentials anyway, and redacting everywhere it gets printed is a sensible backstop. I ran it with --osv-url https://user:pw@127.0.0.1:9 on main and on your branch: on main the password shows up in the terminal, on stderr under --json and in the debug log, and on your branch it shows up nowhere.

Two small things before I approve, both inline.

Since the pattern no longer stops at spaces, a URL with no path now swallows everything up to any later @ on the same line. OSV batch query failed for https://127.0.0.1:9: request to https://api.osv.dev failed, contact admin@example.com comes out as ...request to https://***@example.com. Could you stop the match at @ as well, e.g. [^\s/?#@]+@? For the argv entries, where each one is the whole URL, you could parse it with new URL and blank the username and password if you want to keep the space case covered. A test with an @ later in the message would pin it.

Done, it stops at spaces again and your example now comes out unchanged (added a test for it).

I didn't add @ to the class though, because then a password like p@ss would leave ss showing. For the space case, the argv entries are now parsed with new URL like you suggested.

This one and the Invalid value for --osv-url message in src/cli/validate.ts are the two redactions that still matter after your refusal, since both run before it (on main, --debug writes the password into the log through argv). Neither has a test though: if I undo either change, the suite still passes. Could you add one for each?

Added both, one for the debug log and one for the Invalid value for --osv-url message. Each fails if I undo its fix.

@Skeletor-Pirate

Correction to my review, for accuracy: I traced options.osvUrl and it only ever comes from --osv-url (src/cli/args.ts), with no config-file path, and the new refusal in validateOsvUrl runs inside validateOptions before any OsvAdvisorySource is constructed. So under the CLI the unredacted error.message/stack in the debug payloads cannot carry credentials — the maintainer's walkthrough is right and my "debug log still leaks" framing overstated it.

It is still worth wrapping those two payloads, but as defense-in-depth for direct OsvAdvisorySource construction (tests, future programmatic callers), not as a CLI-visible leak. That should not block approval.

…te paths

The wider match ran past a space to a later @ in the message. Go back to
stopping at whitespace, and mask whole argv entries with new URL instead so
a password with a space is still hidden in the debug log.

Add tests for the CLI started debug log and the invalid --osv-url message.

Do not echo the raw --osv-url value in the invalid-URL error.

When --osv-url fails to parse, the error repeats the full value. The text fallback in redactUrlCredentials stops at whitespace, so a password that contains a space stays visible. The error then shows the username and password in the terminal. The same value also reaches the argv debug payload through redactArgCredentials, which has the same fallback gap.

The error does not need the raw value to be useful. Remove the echo and tell the user what to fix.

Suggested fix

   } catch {
-      throw new Error(`Invalid value for --osv-url: ${redactUrlCredentials(options.osvUrl)}`);
+      throw new Error("Invalid value for --osv-url. Check that it is a valid https:// URL, and remove any username or password from it.");
   }

The argv debug payload at src/index.ts:91 still needs a fix for whitespace-containing userinfo. Make the fallback in redactArgCredentials mask that case too.

Review comment at @src/utils/validate-url.ts around lines 203 - 226:
Update the invalid-URL handling in validateOsvUrl to report how to fix the value without including the raw --osv-url input. Also update redactArgCredentials so its fallback masks username and password when URL userinfo contains whitespace, while preserving the remaining argument text.

When the URL doesn't parse, the arg helper now masks everything up to the last @ (fine there since the arg is just the one value), and the invalid --osv-url error uses that helper too. I kept the URL in the message so it still shows what was wrong, and added tests for https://user:my pass@bad host in both places.

@Medhansh-741 Thanks. The reported example is masked, but a leading space before the URL still exposes the password in the invalid-URL error and debug log.

For example, --osv-url ' https://user:my pass@bad host' reaches the fallback unchanged. The fallback at Line 224 of src/utils/validate-url.ts requires the scheme at the start of the value.

Please handle leading whitespace and add tests for the error and both argv forms. I reproduced the helper behavior with a standalone snippet; I did not run the repository tests. I’m not marking the finding as addressed yet.

You are interacting with an AI system.

If the URL can't be parsed, the arg helper fell back to the text scan,
which stops at spaces, so the invalid --osv-url error and the debug log
could still show it. The fallback now masks up to the last @ of the arg,
and the error uses the same helper.
The fallback for unparseable args stopped at /, ? and #, and needed the
scheme at the very start, so a password like pa/ss, or a value with a
leading space, still showed in the invalid --osv-url error and the debug
log. It now masks from the first scheme up to the last @. A URL that does
parse returns early, so a valid URL with @ in its path is left alone.

malformed HTTPS authorities such as `https:/user:secret@bad host` do not expose
credentials in invalid-value errors or startup debug output; mask credentials
even when `://` is missing, or omit rejected values from output. Add regression

Comment thread src/utils/validate-url.ts Resolved
Masking a malformed URL with a pattern kept missing shapes (spaces, / ? #,
a leading space, https:/). URL credentials always end at an @, so a value
that doesn't parse and has one is now shown as <hidden> in the invalid
--osv-url error and the debug log. Values without an @ are shown as before.

@sonukapoor both points are in now (the pattern stops at spaces again, and there are tests for the argv debug log and the invalid --osv-url message), and CI is green. Could you take another look when you get a chance?
