Alert meAnalysisAIv1 – Mar 12, 2026
The Seraphinite Accelerator WordPress plugin through version 2.28.14 fails to properly validate user permissions on the LogClear AJAX function, allowing authenticated subscribers and higher-privileged users to delete the plugin's debug and operational logs. This capability bypass could enable attackers to cover their tracks or disrupt audit trails on affected WordPress installations. The vulnerability remains unpatched and has not been observed in active exploitation.
