CVE-2025-15690: Unknown Content Mask

Medium severity, CVSS 6.8. EPSS: 0.3% chance of exploitation in the next 30 days.

The Content Mask WordPress plugin before 1.8.5.6 does not properly sanitise and escape content submitted with a post before outputting it in the pages it generates, allowing users with a role as low as Contributor to perform Stored Cross-Site Scripting attacks against any user viewing or previewing the affected page. The Content Mask WordPress plugin before 1.8.5.6's option to restrict its use by role does not prevent this.

Affected products

• Unknown Content Mask: from 1.7.1, before 1.8.5.6 (fixed in 1.8.5.6)
