This vulnerability (CVE-2026-22331) affects ThemeREX AutoParts plugin versions up to 1.5.8 and is caused by improper control of filenames in PHP include/require statements (CWE-98). It allows unauthenticated attackers to perform local file inclusion (LFI), which can lead to remote code execution or disclosure of sensitive information. The CVSS v3.1 base score is 8.1, indicating high severity, with network attack vector, high attack complexity, no privileges required, no user interaction, and high impact on confidentiality, integrity, and availability. No official patch or remediation guidance is currently available from the vendor, and no known exploits are reported in the wild.

Successful exploitation can lead to full compromise of the affected system, including disclosure of sensitive files, remote code execution, and disruption of service. The vulnerability impacts confidentiality, integrity, and availability at a high level. Since the vulnerability is unauthenticated and remotely exploitable, it poses a significant risk to affected installations.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict access to the vulnerable plugin and consider disabling or removing it if possible. Monitor for updates from ThemeREX regarding patches or mitigations.
