Medium (5.8). EPSS 2.4% chance of exploitation in the next 30 days. Fixed in @fonoster/voice 0.6.1.
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.
