# FlyCMS: stored script injection through article content lets attackers run scripts

Link for people: https://infrastack.ai/live/CVE-2026-125082 (this .md is for agents)

FlyCMS, a PHP content management system, does not sanitize the content argument in its article insert path, so a crafted article body is rendered as active script. An attacker can run JavaScript in the browser of anyone who views the affected page.

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

## How to check

- Look for `articles/detail.html` and `ModelDataService.insertData` in your FlyCMS install.
- Check whether your FlyCMS checkout matches commit `e71738e0cfb7ffd48c2ce74242a2dbb43f84f25a` or earlier.

## Fix

- The sources say a patch named `714521a9262e7bc9ca5713c873f57e96a4845352` exists; they give no fixed version because the product uses rolling releases.
