Other vulnerabilities in Content Mask
See all- CVE-2025-15690Medium
The Content Mask WordPress plugin before version 1.8.5.6 does not properly sanitise and escape content submitted with a post before outputting it in the pages it generates. This allows 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 option to restrict its use by role does not prevent this.
- CVE-2026-77003Low
The Content Mask WordPress plugin before version 1.8.5.5 does not check the capability required to publish the post type being created, allowing users with a role as low as Contributor to publish posts and pages without holding the publish capability.
