CVE-2026-16258: CWE-502 Deserialization of Untrusted Data in Ajax Search Lite
Ajax Search Lite WordPress plugin versions before 4.14.5 contain a vulnerability that allows deserialization of untrusted input. This flaw enables unauthenticated attackers to perform PHP Object Injection. If a suitable POP chain is available via another installed Ajax Search Lite plugin before 4.14.5, this vulnerability can lead to Remote Code Execution.
AI Analysis
Technical Summary
The Ajax Search Lite WordPress plugin prior to version 4.14.5 does not properly prevent deserialization of untrusted data, which is classified under CWE-502. This vulnerability allows unauthenticated attackers to perform PHP Object Injection. When combined with a suitable POP chain present in another installed instance of the plugin before 4.14.5, it can be exploited to achieve Remote Code Execution on the affected system.
Potential Impact
Successful exploitation can lead to Remote Code Execution, allowing attackers to execute arbitrary code on the server hosting the vulnerable WordPress plugin. This can compromise the integrity, confidentiality, and availability of the affected system.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the vulnerable plugin and monitor for suspicious activity related to deserialization. Avoid installing multiple instances of the vulnerable plugin to reduce the risk of POP chain exploitation.
