Lifecycle Timeline
2DescriptionCVE.org
The wpForo Forum plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 2.4.13 via deserialization of untrusted input in the 'wpforo_display_array_data' function. This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present.
AnalysisAI
PHP object injection in wpForo Forum plugin versions up to 2.4.13 allows authenticated subscribers and above to deserialize untrusted data, potentially enabling arbitrary file deletion, data theft, or code execution if a POP chain exists in installed plugins or themes. The vulnerability requires an additional gadget chain to be exploitable, making its impact dependent on the broader plugin ecosystem of the target WordPress installation.
