CVE-2026-0910: CWE-502 Deserialization of Untrusted Data in tomdever wpForo Forum
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.
AI Analysis
Technical Summary
CVE-2026-0910 is a deserialization of untrusted data vulnerability (CWE-502) in the wpForo Forum WordPress plugin (versions up to 2.4.13). It allows authenticated users with Subscriber-level privileges or above to inject PHP objects via the 'wpforo_display_array_data' function. However, exploitation requires a gadget POP chain from other plugins or themes to achieve impact such as arbitrary file deletion, sensitive data disclosure, or remote code execution. Without such a POP chain, the vulnerability has no direct impact. The CVSS 3.1 base score is 8.8, indicating high severity.
Potential Impact
If a gadget POP chain is present in other installed plugins or themes, an authenticated attacker with Subscriber-level access can exploit this vulnerability to delete arbitrary files, retrieve sensitive information, or execute arbitrary code. Without such a POP chain, the vulnerability does not lead to impact. There are no known exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict plugin/theme installations to trusted sources to avoid introducing POP chains. Limit user privileges to the minimum necessary and monitor for updates from the wpForo Forum plugin vendor.
