Vulnerability from github – Published: 2026-08-19 15:32 – Updated: 2026-08-19 15:32

Details

phpMyFAQ versions 3.1.0 through 4.1.6 contain an authentication bypass vulnerability in AuthLdap::create(). When LDAP authentication is enabled, after a successful LDAP bind the code calls User::setStatus('active') unconditionally, which overwrites the account_status column of a pre-existing local account from 'blocked' to 'active'. As a result, a user whose local phpMyFAQ account has been administratively blocked can restore their account and log in by authenticating via LDAP. The state transition is not logged, so administrators cannot detect that the block was overridden. Fixed in 4.1.7.

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
