Summary

CVE-2026-80211 is a high-severity Use of Password Hash With Insufficient Computational Effort (CWE-916) vulnerability. Its CVSS base score is 8.2 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Password Cracking (T1110.002); ranked at the 16th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SC-13 (Cryptographic Protection) and IA-5 (Authenticator Management) — see the control section below for these in your framework.

Vulnerability Data

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…

more

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.

T1110.002 Password Cracking Credential Access
Adversaries may use password cracking to attempt to recover usable credentials, such as plaintext passwords, when credential material such as password hashes are obtained.
T1110 Brute Force Credential Access
Adversaries may use brute force techniques to gain access to accounts when passwords are unknown or when password hashes are obtained.

Mitigating Controls (NIST 800-53 r5) AI

Cryptographic protection mandates selection and use of approved algorithms whose parameters can include sufficient work factors for password hashing.

Authenticator management requires secure generation, distribution, and storage of passwords, directly enforcing computationally expensive hashing schemes.

Protection of information at rest requires cryptographic safeguards on stored password hashes, reducing exposure to offline cracking.
