# WordPress Countdown plugin lets authors store scripts that run on pages

Link for people: https://infrastack.ai/live/CVE-2026-111033 (this .md is for agents)

The Countdown, Coming Soon, Maintenance WordPress plugin through 3.0.8 saves countdown data without authorization or nonce checks, and its output filter allows script tags. A user with Author access or higher can store JavaScript that runs for visitors and for administrators who view the affected content.

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

## How to check

- Check whether the plugin `Countdown, Coming Soon, Maintenance` is installed and its version is `3.0.8` or earlier in the WordPress admin plugin list
- Review which accounts hold the Author role or higher, since they can store the script

## From the sources

The Countdown, Coming Soon, Maintenance  WordPress plugin through 3.0.8 does not perform authorization or nonce checks when saving countdown data on post save, and its output-sanitization allowlist permits script tags, allowing users with Author-level access and above to store arbitrary web scripts that execute when the affected content is viewed on the front end or in an administrator session.
