## 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.

Weakness: CWE-79 (Improper Neutralization of Input During Web Page Generation)

What it is: 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.

Affected product: Unknown Content Mask. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
