# Chatwoot: Help Center video links let admins inject scripts into public pages

Chatwoot versions before 4.14.0 do not escape the iframe src attribute built from video-embed links in Help Center articles. An account administrator can craft a link that breaks out of the attribute and runs JavaScript for public visitors, which can steal cw_conversation widget tokens.

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

## How to check

- Check the installed Chatwoot version, for example with `git describe --tags` in the deployment directory or the version shown in the admin settings.
- Look for the render_embed_from_match helper in the Chatwoot source to confirm the unescaped iframe src.

## Fix

- Upgrade Chatwoot to `4.14.0` or later.

## Timeline

## From the sources

Chatwoot before 4.14.0 contains a stored cross-site scripting vulnerability that allows account administrators to inject JavaScript by crafting video-embed links in Help Center articles. Attackers can use angle-bracket link destinations with double quotes to break out of the unescaped iframe src attribute in render_embed_from_match, executing scripts for public visitors and stealing cw_conversation widget tokens.
