CVE-2026-23485Network attack vector

Unauthenticated file enumeration via unvalidated filePath

Published Mar 23, 2026 · Updated Mar 23, 2026

Path traversal in Blinko before 1.8.4 allows remote attackers to enumerate server file existence through the music-metadata API. The public musicMetadata procedure replaces the /api/file prefix with the upload path and passes the unvalidated filePath to fs.promises.readFile, exposing distinct errors for existing and absent paths. The endpoint is unauthenticated but becomes exploitable only when Spotify API credentials are configured; impact is limited to confirming paths, not reading file contents.
