Pasting content copied from malicious websites into the Froala richeditor could result in a successful self-XSS attack.
Issue has been patched in Build 467 (v1.0.467).

If you have any questions or comments about this advisory:
Assessed as Low given that by the nature of the attack it can only impact users that do it to themselves by copying and pasting from malicious websites.
