WordPress Plugin Peter's Math Anti-Spam is prone to a security bypass vulnerability. This issue occurs when presenting a visitor with challenge data to determine if they are a legitimate user or an automaton. The challenge data is poorly obfuscated and can be interpreted by script code. Attackers can leverage this issue to bypass the security measures provided by the plugin via an automated script. This could aid in spam distribution and other attacks. WordPress Plugin Peter's Math Anti-Spam version 0.1.6 is vulnerable; other versions may also be affected.
