Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Affected versions of the Packagist package thorsten/phpmyfaq from 4.0.7 before 4.0.13 do not enforce email uniqueness during user registration, so several accounts can share one email address. The source says an attacker can register multiple accounts with the same email, and that this may enable account takeover or privilege escalation where email drives password resets or admin flows, though the source gives few details on how these outcomes occur. Upgrade to version 4.0.13, which is the listed fixed version.
