{"id":"GHSA-763j-3p5v-jfc6","summary":"androidqf: APK download Path Traversal in device APK paths","details":"### Summary\nDuring 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.\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","aliases":["GO-2026-5206"],"modified":"2026-06-25T19:56:40.658744692Z","published":"2026-05-21T17:11:47Z","database_specific":{"severity":"LOW","github_reviewed":true,"github_reviewed_at":"2026-05-21T17:11:47Z","nvd_published_at":null,"cwe_ids":["CWE-22"]},"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"}],"affected":[{"package":{"name":"github.com/mvt-project/androidqf","ecosystem":"Go","purl":"pkg:golang/github.com/mvt-project/androidqf"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"1.8.3"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/05/GHSA-763j-3p5v-jfc6/GHSA-763j-3p5v-jfc6.json","last_known_affected_version_range":"\u003c= 1.8.2"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U"}]}
