## What is CVE-2026-10108?

CVE-2026-10108 is a high-severity path traversal vulnerability in hanxi xiaomusic, published on 29 May 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

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.

Weakness: CWE-22 (Improper Limitation of a Pathname to a Restricted Directory)

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
