What changed and why

When an advisory defines multiple version windows, extractAffectedRange in src/output/sarif.ts previously returned only the first fixed event from the first window, producing inaccurate rule help for packages fixed in later windows (e.g., displaying < 1.4.0 for a package on the 2.x branch fixed in 2.1.0).

• Updated extractAffectedRange to parse all windows from advisory SEMVER ranges and match the installed package version against them using semver satisfiability.
• Formats each window preserving any explicit lower bound (>= 1.0.0 < 1.4.0) or omitting it for unbounded windows (< 1.4.0).
• When the installed version matches a window, returns that window's affected range and fixed version.
• When no window matches or no version is provided, returns all windows joined with or (< 1.4.0 or >= 2.0.0 < 2.1.0) and lists the fixed versions.
• Passes finding.pkg.version and finding.pkg.name from buildSarifOutput into buildRuleHelp.

Verification

• Added unit and integration tests under tests/sarif/affected-range.test.ts:
  • Single-window advisory with introduced: "0"
  • Single-window advisory with explicit introduced
  • Multi-window advisory where version falls in second window
  • Multi-window advisory where version falls in first window
  • Version not matching any window (combined description)
  • Unspecified installed version (combined description)
  • Multi-window advisory split across multiple SEMVER range objects
  • Full buildSarifOutput rule help verification with multi-window finding
• Verified test hygiene (npm run lint:tests), build (npm run build), and test execution (tests/sarif/affected-range.test.ts, tests/sarif.test.ts).

Closes #1664

Summary

Summary by CodeRabbit

• Bug Fixes
  • SARIF reports now include affected and patched version ranges across multiple version windows, including ranges with “last affected” bounds.
  • When the installed version matches a range, the report shows the affected and patched versions for that range. Package-matching ranges are preferred when available.
  • Version matching now accounts for prereleases and can retry using a normalized installed version.

For SARIF consumers, rule help now reports the affected window that matches the finding’s installed version when possible. The extraction parses and formats OSV SEMVER windows, and the tests cover matching windows and combined ranges.

Changes: SARIF affected-range selection

Layer / File(s)	Summary
Parse and select affected windows src/output/sarif.ts, tests/sarif/affected-range.test.ts	The extraction builds windows from OSV SEMVER events, formats and deduplicates the ranges, and selects the installed version’s matching window when available. Unit tests cover single and multiple windows, matching and unmatched versions, and missing fixed ranges.
Pass finding details to rule help src/output/sarif.ts, tests/sarif/affected-range.test.ts	Rule-help construction passes the finding’s package name and installed version to range extraction. An output test checks that the help uses the matching window’s affected range and patched version.

Estimated code review effort: 3 (Moderate) | ~25 minutes

SARIF rule help can still show an affected range or patched version from the wrong advisory window. This happens for multi-window advisories, aliased packages, prereleases and later findings of the same advisory. The new integration test also has a type error that will fail the CI type-check. Fix these before merging; scan results themselves are not affected.

Full details: Title check

Explanation

The title follows the required "type: short description" form with the fix type, lowercase after the colon, and no trailing period. It names the change accurately: selecting the matching window in SARIF rule help for multi-window advisories. The title is 90 characters, which is long, but it does not affect the check. The title does include a "(#1664)" issue reference, which is extra but harmless.

Full details: Linked Issues check

Explanation

For users, SARIF rule help now shows the range that matches their installed version. I checked the reviewed head against the merge base. Issue #1664 has four coding requirements, and each one is implemented in src/output/sarif.ts:

1. Select the matching window. extractAffectedRange parses every window from the SEMVER events. It returns the first window that satisfies the installed version, using matchesWindow. Test: "selects the second window when installed version falls in the second window" (2.0.5 gives >= 2.0.0 < 2.1.0).
2. Combine all windows when none matches. Without a match, or with no installed version, the code returns windows.map(...).join(" or ") and the joined fixed versions. Tests: the unmatched 3.0.0 case and the no-version case both expect < 1.4.0 or >= 2.0.0 < 2.1.0.
3. Preserve introduced. formatRange emits >= introduced for non-zero lower bounds and omits it for 0. Test: >= 1.0.0 < 1.4.0.
4. Single-window coverage. Tests cover both introduced: "0" and explicit introduced.

The issue asks for tests of these cases under tests/sarif/. The file tests/sarif/affected-range.test.ts covers them. It also covers windows split across several SEMVER range objects and a full buildSarifOutput rule help check. I did not run the test suite. This verdict rests on the source and test code I read.

Full details: Out of Scope Changes check

Explanation

All changes in the diff support the fix for #1664, or are tests for it. Three behaviors go a little beyond the issue text:

• Package-name filtering. extractAffectedRange prefers affected entries whose package.name matches the finding. This keeps windows from other packages out of the rule help. It supports the same goal of an accurate range.
• Deduplication and fallbacks. Identical formatted ranges are removed. The function returns null when no fixed version exists. Prerelease handling and a coerced-version retry are also added. These details decide which window matches, so they are part of the same change.
• The export on extractAffectedRange. This makes the function testable. The new semver import is already a declared dependency in package.json, so no dependency change is needed.

The diff does not touch unrelated output, scan, or fix logic. I found no concrete unrelated change.

Full details: Description check

Explanation

The description follows the repository template. It has the "What changed and why" section with a clear summary of the fix, the reason for it (inaccurate rule help for packages fixed in later windows), and a list of behavioral changes. It also has a Verification section listing the added tests and commands run. The "Closes #1664" line matches the template's issue reference, and the linked objectives confirm that issue. The template's placeholder comment was replaced with real content.

Full details: Linked Issue

Explanation

I checked the pull request body. It contains "Closes #1664" in the "Closed" line at the end of the description. That matches the Closes keyword followed by a GitHub issue number, so the check passes. Issue #1664 is the linked issue. The linked-issue context confirms that it describes the same SARIF affected-range problem this PR addresses. The check only tests the body reference, so I did not inspect the code changes. I wrote this from the supplied PR description. I did not run repository tools, because the reference is in the text I was given.

Full details: No New Runtime Dependency

Explanation

I checked the reviewed diff range (refs/coderabbit/pre-merge-check/base to head). It changes two files: src/output/sarif.ts (modified) and tests/sarif/affected-range.test.ts (added). package.json is not in the changed-file list, and the diff for it is empty. No lockfile changed either. The PR therefore adds no entry to dependencies or optionalDependencies and does not move a package from devDependencies into dependencies. The check passes. The PR author is bhushan4work, but the check does not depend on author identity. The review comments on sarif.ts concern parsing and selection logic, not dependency changes, so they do not affect this check.

Full details: Closes Keyword Matches Scope

Explanation

The PR body uses Closes #1664, so merging auto-closes issue #1664. I read the linked issue. It asks for these items: 1. extractAffectedRange selects the window matching the installed version, or combines all windows. Delivered. src/output/sarif.ts now parses all SEMVER windows, selects a match with matchesWindow, and falls back to joining all windows with " or ". 2. Preserve introduced bounds when present. Delivered. formatRange emits >= introduced for non-sentinel values. 3. Tests for a single-window advisory, a match in a later window, and no matching window. Delivered in tests/sarif/affected-range.test.ts, which is a new file. 4. Checklist: "Code passes npm test". Not delivered. Finding.firstFixedVersion is a required field (src/types.ts:186, string | null). The integration fixture in tests/sarif/affected-range.test.ts (around line 215) builds a Finding without that field. A repository search finds no firstFixedVersion in the test file. The CI build diagnostic reports the same type error. So the new test file does not type-check and the suite does not pass as the issue requires. Secondary gap. buildSarifOutput caches rule help per advisory ID in ruleMap (around lines 453-466). buildRuleHelp runs only for the first finding of an advisory. A later finding of the same advisory with an installed version in a different window receives the first finding's window. The issue expects the window matching the installed version, so this path is only partly covered. Items "Reproduced locally", "Updated documentation if applicable", and "Linked issue in PR description" are process items. The PR links the issue, and I found no documentation the change requires. Result: the core behavior and tests are present. The checklist item that the code passes npm test is not met. Because merging would close #1664 with that item unmet, the Closes keyword does not match the delivered scope.

Resolution

The author should fix the scope gap before merging, or switch the keyword to Refs. 1. Add the required firstFixedVersion field to the Finding fixture in tests/sarif/affected-range.test.ts. Keep the Finding annotation. Run npm test and the type-check, and confirm they pass. 2. Decide how shared rule help should handle several installed versions of one advisory. Either keep aggregate help in ruleMap and put the selected window in result-specific text or metadata, or add a test that documents the accepted limit. Then confirm that the SARIF output matches the issue's expected behavior. 3. After both items pass, Closes #1664 is valid. If any item stays open, change the body to Refs #1664.

Order events before pairing introductions and fixes.

OSV permits unsorted events; its evaluation algorithm sorts them before use. (ossf.github.io)

For [introduced: 0, introduced: 2.0.0, fixed: 1.4.0, fixed: 2.1.0], this parser creates >= 2.0.0 < 1.4.0 and < 2.1.0. Installed version 1.2.0 then receives patch 2.1.0 instead of 1.4.0.

I would sort a copy with semantic-version ordering and handle the "0" sentinel before constructing windows.

Preserve an explicit 0.0.0 introduction.

An advisory with introduced: "0.0.0" and fixed: "1.0.0" currently reports < 1.0.0. It should retain >= 0.0.0. OSV reserves "0", not "0.0.0", for the unbounded introduction sentinel. (ossf.github.io)

I would remove the "0.0.0" exception. This also follows the PR requirement to preserve explicit lower bounds.

Preserve prerelease identity when selecting a window.

With windows [2.0.0, 2.1.0) and [2.0.0-beta.1, 2.0.0-beta.3), installed version 2.0.0-beta.2 incorrectly selects the first window. The first comparison fails, but default coerce removes the prerelease suffix and retries as 2.0.0. The declared minimum version, semver 7.8.5, implements this behavior. (raw.githubusercontent.com)

I would return the original comparison result for valid semantic versions. Restrict coercion to inputs that cannot be parsed, and preserve prerelease information during that fallback.

Do not label another window's fix as the selected window's patch.

For events introduced: 0, fixed: 1.4.0, introduced: 2.0.0, installed version 2.0.4 returns Affected: >= 2.0.0 with Patched: 1.4.0. The selected window has no fixed event.

I would report that no patch is specified for that window instead of substituting fixes from other windows.

Keep finding-specific windows out of shared rule help.

When two installed versions match different windows of the same advisory, the second result inherits the first result's affected range and patched version. ruleMap caches help by advisory ID, so this call only runs for the first finding.

I would keep aggregate advisory ranges in shared rule help and put the selected window in result-specific metadata or text.

Pass the registry name when selecting an advisory window for an alias.

For an npm alias, finding.pkg.name holds the alias, while the OSV advisory lists the registry package. The package filter in extractAffectedRange then matches no entries and scans every package in the advisory. If another package in the same advisory appears first, the rule help can show that package's affected range and fixed version for the aliased dependency.

Pass the registry name, which falls back to the plain name for non-alias packages:

Add firstFixedVersion to the integration fixture.

This fixture fails type-checking because Finding.firstFixedVersion is required. The supplied build diagnostic reports the same missing property.
