Deserialization of Untrusted Data vulnerability in Marcus (aka @msykes) Events Manager events-manager allows Object Injection.This issue affects Events Manager: from n/a through <= 7.3.6.
AnalysisAI
PHP Object Injection in the WordPress Events Manager plugin (Marcus/@msykes) affects all versions up to and including 7.3.6, letting remote attackers deserialize untrusted data and instantiate arbitrary PHP objects. When paired with a suitable POP gadget chain present in the plugin, WordPress core, or another installed plugin, this can escalate to remote code execution, data theft, or site takeover. Reported by Patchstack with a CVSS of 8.8; there is no public exploit identified at time of analysis and it is not on CISA KEV, though the network vector combined with only requiring user interaction makes it a serious patch priority.
