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.\n\nPractical 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.\n\n### Impact\nAn 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.\n\n### Patched version\n[1.8.3](https://github.com/mvt-project/androidqf/releases/tag/v1.8.3)\n\n### Credits\n- This issue was identified during a security assessment conducted by 0xche. \n- An additional vulnerability was independently identified by @0x0v1","published":"2026-05-21T17:11:47Z","modified":"2026-06-25T19:56:40.658744692Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/mvt-project/androidqf","fixedVersion":"1.8.3"}],"fix":null,"references":[{"type":"WEB","url":"https://github.com/mvt-project/androidqf/security/advisories/GHSA-763j-3p5v-jfc6"},{"type":"PACKAGE","url":"https://github.com/mvt-project/androidqf"},{"type":"WEB","url":"https://github.com/mvt-project/androidqf/releases/tag/v1.8.3"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-06-25T19:56:40.658744692Z"}}
