What is GHSA-763j-3p5v-jfc6?
GHSA-763j-3p5v-jfc6 is a path traversal vulnerability in github.com/mvt-project/androidqf, published on 21 May 2026. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Official description
Summary
During device acquisition, getPathToLocalCopy() constructs local filesystem paths for downloaded APKs using a filename component extracted by extractFileName(). The extraction splits on ==/ and takes the remainder without sanitization. If a compromised device returns a crafted APK path containing traversal sequences, filepath.Join resolves them, allowing the file to be written outside the intended apks/ directory.
Practical exploitability is limited because Android enforces strict package path formats under /data/app/ and does not allow apps to register paths containing traversal sequences. Rated Informational as a defense-in-depth concern.
Impact
An attacker with control of the connected device could potentially write files outside the expected output directory on the acquisition workstation, leading to arbitrary file overwrite with attacker-controlled content.
