Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Codiad versions up to and including 2.8.4 are vulnerable to an authentication bypass in the Authenticate() function of its user class. Because of PHP "magic hash" comparison, certain password hashes that look like scientific notation can match other hashes, so a different password may log in successfully. The source gives few details on the exact conditions or the attacker's requirements. No fixed version is listed.
