WordPress vulnerability analysis and mitigation

The Theme Editor plugin for WordPress (versions up to and including 2.8) contains a deserialization vulnerability (CVE-2022-2440) that affects the 'images_array' parameter. This vulnerability was disclosed on August 29, 2024 (NVD).

The vulnerability is classified as a deserialization of untrusted data (CWE-502) issue. It has received a CVSS v3.1 base score of 7.2 (High) with the vector string CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H. The vulnerability allows authenticated attackers with administrative privileges to use PHAR wrapper for deserializing and calling arbitrary PHP Objects, provided a POP chain is present (NVD).

When successfully exploited, this vulnerability could allow attackers to perform various malicious actions through the deserialization of arbitrary PHP Objects. The impact is considered high for confidentiality, integrity, and availability, as indicated by the CVSS score (NVD).

The vulnerability requires an authenticated attacker with administrative privileges and the ability to successfully upload a file containing the serialized payload. The attack complexity is considered low, but the prerequisite of administrative access somewhat limits the potential scope of exploitation (NVD).

Users should upgrade to a version newer than 2.8 of the Theme Editor plugin to address this vulnerability (NVD).
