# Edito CMS: stored XSS through avatar upload lets attackers run scripts

Link for people: https://infrastack.ai/live/CVE-2026-59078 (this .md is for agents)

Edito CMS does not properly sanitize avatar uploads, so HTML and JavaScript can be stored and then run in the browser of anyone who visits a URL pointing to the edited avatar. An attacker with an account can use this to run scripts in other visitors' browsers.

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

## How to check

- Check the installed Edito CMS version against the fixed release `5.10.2607` or the hotfix for `5.8`
- Review whether user avatar uploads are enabled in the Edito CMS configuration (unknown if the sources name the setting)

## Fix

- Upgrade Edito CMS to `5.10.2607` or later
- Hotfixes for older versions (`5.8`) have also been released; exact hotfix version unknown

## Timeline
