Vulnerability Details CVE-2026-37531
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. 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.
