The vulnerability CVE-2026-22451 affects AncoraThemes Handyman plugin versions up to 1.4.7. It is caused by unsafe deserialization of untrusted data, enabling an attacker to perform object injection. This can result in remote code execution or other severe impacts on the affected system. The CVSS 3.1 base score is 9.8, reflecting critical impact on confidentiality, integrity, and availability with an attack vector over the network and no required privileges or user interaction. No patch or vendor advisory details are currently available to confirm remediation status.

Successful exploitation of this vulnerability could allow an unauthenticated attacker to execute arbitrary code remotely, leading to full compromise of the affected system’s confidentiality, integrity, and availability. Given the critical CVSS score and the nature of object injection via deserialization, the impact is severe.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, it is recommended to restrict access to the vulnerable plugin and monitor for suspicious activity related to deserialization processes. Avoid using untrusted data in deserialization routines if possible.
