CVE-2026-49769

Name of the Vulnerable Software and Affected Versions wpForo Forum versions prior to 3.1.1

Description The wpForo Forum plugin for WordPress allows unauthenticated attackers to perform PHP Object Injection through the deserialization of untrusted input. PHP Object Injection occurs when an application deserializes data from an untrusted source, potentially allowing an attacker to manipulate the object's properties. While no POP chain (a sequence of gadgets used to achieve code execution) is present in the software itself, the presence of a POP chain in other installed plugins or themes could enable the deletion of arbitrary files, retrieval of sensitive data, or remote code execution.

Recommendations Update wpForo Forum to a version newer than 3.1.0.
