AI-suggested

Users should upgrade to version 8.3.0 or later once released. Until then, sites should ensure their WordPress nonce key is properly set to a strong, secret value to reduce the risk of key predictability. Monitor the vendor advisory for updates and apply official fixes when available.

Description

The Site Reviews WordPress plugin before 8.3.0 does not prevent request data from being deserialized, and derives the key protecting that data by padding out the site's WordPress nonce key, which makes the key publicly computable on installs where that key is absent, left at its sample value, or too short to be secret. This allows unauthenticated users to inject arbitrary PHP objects on such installs. The Site Reviews WordPress plugin before 8.3.0's own code contains no chain onward from the injected object, so how far it reaches depends on the other code present on the site.

Impact

Unauthenticated attackers can inject arbitrary PHP objects via deserialization, potentially leading to remote code execution or other impacts depending on the presence of other vulnerable code on the site. The plugin itself does not provide a direct exploitation path, so the severity of impact varies with the site's environment and additional installed code.

Summary

CVE-2026-82925 is a deserialization of untrusted data vulnerability (CWE-502) in the Site Reviews WordPress plugin versions before 8.3.0. The plugin improperly allows deserialization of request data using a key derived from the WordPress nonce key, which can be predictable or publicly computable on some installs. This flaw enables unauthenticated attackers to inject arbitrary PHP objects. The plugin's own code does not directly exploit the injected objects, so the actual impact depends on other plugins or code on the site that may interact with these objects.
