CVE-2026-82925
HighCVSS 8.1Exploitation Probability (EPSS)
Low risk21th percentile - higher than 21% of all known CVEs
Summary
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 plugin'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.
Risk Assessment
An unauthenticated attacker could inject arbitrary PHP objects, and the extent of the attack depends on other code present on the site, potentially leading to further compromise.
Recommendation
Update the Site Reviews plugin to version 8.3.0 or later.
