CVE-2026-16297: CWE-502 Deserialization of Untrusted Data in Clearfy Cache
The Clearfy Cache WordPress plugin before 2.4.3 does not restrict the classes allowed when unserializing settings-import data, allowing users with administrator access to perform PHP Object Injection attacks, which may lead to remote code execution when a suitable gadget chain is present in the environment.
AI Analysis
Technical Summary
The Clearfy Cache WordPress plugin prior to version 2.4.3 contains a deserialization vulnerability (CWE-502) where it does not restrict classes during unserialization of settings-import data. This flaw enables administrator-level users to execute PHP Object Injection attacks, which may result in remote code execution when combined with an appropriate gadget chain present in the environment. The vulnerability is documented under CVE-2026-16297. There is no CVSS score or vendor advisory indicating a patch or fix at this time.
Potential Impact
An attacker with administrator access can exploit this vulnerability to perform PHP Object Injection, potentially leading to remote code execution. This could allow the attacker to execute arbitrary code on the server hosting the WordPress site, compromising the integrity and confidentiality of the system. The impact depends on the presence of a suitable gadget chain in the environment.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict administrator access to trusted users only and monitor for updates from the Clearfy Cache plugin vendor. Avoid importing untrusted settings data.
