MediumCVSS 4.3Exploitation Probability (EPSS)
Low risk3th percentile - higher than 3% of all known CVEs
Summary
Missing nonce validation in the msp-options.php script of the WP Meta Sort Posts plugin for WordPress allows CSRF attacks. An unauthenticated attacker can change plugin settings (msp_loop_file and msp_nav_location) via a forged request if they trick an admin into clicking a link.
Risk Assessment
An attacker can alter plugin configuration, potentially leading to site malfunction or code injection.
Recommendation
Update the plugin to the latest version that includes proper nonce validation.

- CVE-2026-124494Critical
SunEditor before 3.4.0 contains a stored cross-site scripting vulnerability because the html.clean() sanitizer's _normalizeURL() function decodes named entities like : to an empty string.

SunEditor before 3.4.0 contains a stored cross-site scripting vulnerability in the DocumentType constructor that injects header textContent into innerHTML without HTML escaping. Attackers can store entity-encoded HTML in h1-h6 headers that executes JavaScript when editors using document:header mode initialize, enabling session cookie theft.
Original NVD description (English source)
The WP Meta Sort Posts plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 0.9. This is due to missing or incorrect nonce validation on the top-level included script in msp-options.php. This makes it possible for unauthenticated attackers to change the plugin's msp_loop_file and msp_nav_location settings via a forged request via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
