{"id":"CVE-2026-80211","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-80211","summary":"FrontAccounting through 2.4.20 stores and verifies user passwords as unsalted MD5 digests. admin/users.php passes md5($_POST['password']) to add_user() and update_user_password(), admin/change_current_user_password.php…","details":"FrontAccounting through 2.4.20 stores and verifies user passwords as unsalted MD5 digests. admin/users.php passes md5($_POST['password']) to add_user() and update_user_password(), admin/change_current_user_password.php does the same when a user changes their own password, the forgotten-password path in includes/current_user.inc hashes the newly generated password the same way, and authentication calls get_user_auth($loginname, md5($password)). The codebase applies no per-password salt and contains no call to password_hash(), password_verify() or any other adaptive hash, so identical passwords yield identical digests and an attacker who obtains the user table can recover plaintext passwords with precomputed lookup tables or high-rate GPU cracking.","published":"2026-08-27T17:20:50.733","modified":"2026-08-27T17:20:50.733","cvss":{"score":5.9,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://github.com/FrontAccountingERP/FA"},{"type":"WEB","url":"https://github.com/FrontAccountingERP/FA/blob/9464a3ffef03c139d9396e697bce9a0a9f131a72/includes/current_user.inc#L79"},{"type":"WEB","url":"https://github.com/geo-chen/oss/blob/main/FA.md#finding-2-unsalted-md5-password-hashing-in-frontaccounting"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/frontaccounting-through-2.4.20-use-of-unsalted-md5-for-password-storage"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-27T17:20:50.733"}}
