CVE-2026-15939: Unknown Simple Restrict

Low severity, CVSS 2.7. EPSS: 0.3% chance of exploitation in the next 30 days.

The Simple Restrict WordPress plugin before 1.2.9 does not enforce its content-restriction permission check on the REST API the way it does on the front end, relying there on a generic capability check instead of the Simple Restrict WordPress plugin before 1.2.9's own permission system, allowing users with contributor-level access or above to read the content of restricted posts and pages they were never granted access to.

Affected products

• Unknown Simple Restrict: before 1.2.9 (fixed in 1.2.9)
