Wordfence Argus Identifies Two Critical Unauthenticated Vulnerability Chains Leading to Remote Code Execution in The Events Calendar Plugin
Matched: WordPress
Wordfence discovered two critical unauthenticated remote code execution vulnerability chains in The Events Calendar WordPress plugin, active on over 600,000 sites. Both chains exploit the plugin's widget-rendering pipeline, triggered via pending comment previews without moderator approval, requiring only that comments be enabled on event pages. The first uses PHP Object Injection; the second abuses an arbitrary PHP callable to reset an admin password. Users should update to version 6.17.4.1 immediately.
