Canonical #1055 already owns the stronger path-free log sink and a stricter caplog regression covering decoder failure without local-path disclosure; #1237 preserves the separate bounded caller-visible diagnostic finding.

While the frontend enforced `MAX_YOUTUBE_URL_LENGTH = 2000` via the input element, this could be bypassed by an attacker sending requests directly to the Tauri backend API, potentially causing a Denial of Service (DoS) due to unbounded URL parsing and regex matching. **Learning:** Input validation must occur at the entry point of untrusted data on the backend, even if it is also validated on the frontend. Relying solely on frontend validation for constraints like string length can expose the backend to resource exhaustion vulnerabilities. **Prevention:** Always enforce constraints like maximum length, format validation, and sanitization at the earliest possible point on the backend, typically at the API boundary, regardless of frontend safeguards. -## 2026-09-24 - Path-Free Log Sink Privacy Boundary -**Vulnerability:** Untrusted user input (like file paths) and raw exceptions were logged directly using f-strings, exposing sensitive local paths and allowing potential log forging/injection if the input contains control characters like newlines. -**Learning:** While using `repr()` escapes control characters to prevent log forging, it still leaks sensitive local paths into the log sink.
