March 5, 2026 (updated March 6, 2026)

Fonoster 0.5.5 before 0.6.1 allows ../ directory traversal to read arbitrary files via the /sounds/:file or /tts/:file VoiceServer endpoint. This occurs in serveFiles in mods/voice/src/utils.ts. NOTE: serveFiles exists in 0.5.5 but not in the next release, 0.6.1.
