What is CVE-2025-15690?
CVE-2025-15690 is a medium-severity cross-site scripting vulnerability in Unknown Content Mask, published on 9 Sep 2026. An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.
Official description
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.
