CVE-2026-28139 is a critical vulnerability in the wpdreams Ajax Search Lite plugin, affecting versions up to and including 4.14.4. It involves unauthenticated PHP Object Injection due to deserialization of untrusted data (CWE-502). This flaw allows an attacker to execute arbitrary code remotely without any authentication.
AI Analysis
Technical Summary
This vulnerability in Ajax Search Lite (<=4.14.4) arises from unsafe deserialization of untrusted data, enabling unauthenticated PHP Object Injection. The CVSS 3.1 score of 9.8 reflects its critical nature with network attack vector, no required privileges or user interaction, and high impact on confidentiality, integrity, and availability. No official patch or remediation level is currently documented, and no known exploits in the wild have been reported as of the publication date.
Potential Impact
Successful exploitation can lead to remote code execution with full impact on confidentiality, integrity, and availability of the affected system. Since no authentication is required, attackers can exploit this vulnerability remotely over the network, making it highly severe.
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 attempts.
