 **Vulnerability:** The Rust backend (`apps/desktop/src-tauri/src/main.rs`) did not enforce a maximum URL length limit when processing YouTube URLs via `import_youtube_url`. 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.

+## 2024-05-22 - [CSV Formula Injection NUL Byte Bypass]
+**Vulnerability:** A missing NUL byte check in the CSV formula injection detection logic.
+**Learning:** Control characters like NUL bytes (`\x00`) can bypass simple leading-character checks for formula injection payloads.
+**Prevention:** Always include NUL bytes in the regular expression or string check alongside `\t`, `\n`, `\r`, and leading whitespace when preventing CSV formula injection.

 ### Added
 
-- Name tonight's first playable range on the ready rehearsal map and tell the player to check that span on their instrument before the section.
 - Display the analyzed song tempo (BPM) as a badge in the rehearsal workspace.
 - 각 합주 역할(Role)별 개인 연습 진행도를 0~100% 범위로 기록 및 시각화할 수 있는 연습 진척도(`practiceProgress`) 트래커 기능 추가. UI 컨트롤(슬라이더 및 +/- 버튼)과 한/영 다국어 지원 포함.
 
-### Changed
-
-- Pinned npm `10.9.9` as the approved lockfile generator, activated it through Node-bundled Corepack before dependency consumption, and fail closed unless its bundled `tar` is at least `7.5.19`; primary CI still consumes the committed lock only through frozen `npm ci` validation, rejects mutable npm resolution in the lock gate, requires integrity evidence for public-registry lock entries, and preserves generator-sensitive root `@esbuild/*` peer metadata.
-
-### Fixed
-
-- Upgraded the local score PDF parser to `pdfjs-dist` 6.2.108, pinned Undici 7.29.0 across the workspace, and constrained PDF loading to copied in-memory bytes with a same-origin bundled worker and npm-generated lock provenance.

Tauri commands (`start_analysis_job`, `get_analysis_job_status`, `select_local_audio_source`, `import_youtube_url`) validate untrusted input (project IDs, file paths, URLs) and spawn the Python engine as a subprocess. There is no loopback HTTP listener and no network path for local analysis.
