The is_valid_filename function in wgtpkg-zip.c validates ZIP entry names but does not check for dot notation directory traversal sequences it only blocks absolute paths. The zread extraction function uses openat(workdirfd, filename, O_CREAT) which resolves dot notation values relative to the work directory, allowing files to be written anywhere on the filesystem. Critically, in function install_widget in file wgtpkg-install.c, extraction via zread occurs BEFORE signature verification via check_all_signatures. Even if signature verification fails, the error cleanup (remove_workdir) only deletes the temporary work directory files written outside via path traversal persist permanently.","publishedAt":"2026-05-01T00:00:00.000Z","updatedAt":"2026-05-01T19:45:23.782Z","severity":{"score":9.8,"label":"Critical","version":"3.1","vector":"CVSS:3.1/AC:L/AV:N/A:H/C:H/I:H/PR:N/S:U/UI:N","source":"mitre"},"assigner":"mitre","products":["n/a n/a"],"affected":[{"vendor":"n/a","product":"n/a","versions":[{"version":"n/a","status":"affected"}]}],"references":["https://gerrit.automotivelinux.org/gerrit/src/app-framework-main","https://gist.github.com/sgInnora/8526eedcfd826d05ef1fc45d8f405643"],"weaknesses":["CWE-22","CWE-367"],"ingestedAt":"2026-10-29T20:11:50.837Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/37xxx/CVE-2026-37531.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-37531","state":"PUBLISHED","datePublished":"2026-05-01T00:00:00.000Z","dateUpdated":"2026-05-01T19:45:23.782Z","assignerShortName":"mitre","assignerOrgId":"8254265b-2729-46b6-b9e3-3dfca2d5bfca","dateReserved":"2026-04-06T00:00:00.000Z"},"containers":{"cna":{"descriptions":[{"lang":"en","value":"AGL app-framework-main thru 17.1.12 contains a Zip Slip path traversal vulnerability (CWE-22) combined with a TOCTOU race condition (CWE-367) in the widget installation flow.
