CVE-2026-10035: CWE-502 Deserialization of Untrusted Data in wpweaver Turnkey bbPress by WeaverTheme
The Turnkey bbPress by WeaverTheme plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.7.1 via deserialization of untrusted input in the wvrbbp_set_to_serialized_values() function (reached through the wvrbbp_save_restore() settings-restore handler). The function reads the raw contents of an administrator-uploaded file and passes them directly to unserialize() without any validation. This makes it possible for authenticated attackers, with administrator-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable plugin itself; however, if a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.
AI Analysis
Technical Summary
CVE-2026-10035 is a PHP Object Injection vulnerability in the Turnkey bbPress by WeaverTheme WordPress plugin affecting all versions up to 1.7.1. The vulnerability occurs in the wvrbbp_set_to_serialized_values() function, which deserializes untrusted input from administrator-uploaded files without validation. While no POP chain is present in the plugin itself, the presence of a POP chain in other installed plugins or themes could enable an attacker with administrator privileges to perform destructive or unauthorized actions such as arbitrary file deletion, data disclosure, or remote code execution.
Potential Impact
An attacker with administrator-level access can exploit this vulnerability to inject PHP objects via deserialization, potentially leading to high-impact consequences including arbitrary file deletion, sensitive data exposure, and remote code execution, depending on the presence of gadget chains in other installed components.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict administrator file uploads and review installed plugins and themes for potential POP chains that could be leveraged. Monitor for updates from the vendor and apply official patches once released.
