AI Analysis
Technical Summary
CVE-2026-8940 is a CSRF vulnerability in the WP Meta Sort Posts plugin for WordPress, affecting all versions up to 0.9. The vulnerability arises from missing or incorrect nonce validation on the top-level included script in msp-options.php.

The vulnerability has a CVSS 3.1 base score of 4.3, indicating medium severity. No patch or official fix has been documented, and the plugin is not a cloud service, so remediation depends on vendor updates or manual mitigation.

The impact is limited to integrity as no confidentiality or availability impact is indicated. There is no evidence of active exploitation in the wild.
