# CleanTalk Anti-Spam WordPress plugin: unescaped comment value runs script in admin browser

Link for people: https://infrastack.ai/live/CVE-2026-115673 (this .md is for agents)

The Anti-Spam, Spam FireWall by CleanTalk WordPress plugin before 6.91 outputs a commenter-supplied value on an admin spam-review screen without escaping it. An unauthenticated visitor can plant a script there that runs in the browser of an administrator who reviews flagged comments.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed plugin version in the WordPress admin under Plugins, or with `wp plugin get cleantalk-spam-protect --field=version` (unknown if the sources do not name the plugin slug)
- Look for the plugin on sites where administrators review flagged comments in the spam queue

## Fix

- CleanTalk Anti-Spam plugin: move to `6.91` or later

## Timeline

- 2026-11-06T06:40:11+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-115673

## From the sources

The Anti-Spam, Spam FireWall by CleanTalk WordPress plugin before 6.91 does not escape a commenter-supplied value before outputting it on an administrative spam-review screen, allowing unauthenticated users to inject arbitrary web scripts that execute in the browser of an administrator who reviews flagged comments.
