xiaomusic v0.5.7 contains an unauthenticated path traversal vulnerability in the GET /music/{file_path:path} endpoint that allows unauthenticated attackers to read arbitrary files outside the intended music directory by exploiting an incomplete path prefix check. Attackers can request files from sibling directories whose names share the music_path prefix by crafting traversal sequences, bypassing the path restriction due to the missing trailing separator in the comparison logic to retrieve arbitrary files from the server.
AnalysisAI
Path traversal in xiaomusic v0.5.7 allows unauthenticated attackers to read arbitrary files outside the intended music directory via the GET /music/{file_path:path} endpoint. The flaw stems from an incomplete path prefix check that lacks a trailing separator, enabling bypass through sibling directories. Public proof-of-concept code exists; EPSS estimates a low 0.18% probability of exploitation, and no active exploitation has been confirmed by CISA KEV.
