Description OSIDB Bzimport 2026-09-29 20:37:26 UTC 
A flaw was found in Moodle. Insufficient escaping of the username on the password reset page allowed a minor cross-site scripting (XSS) risk if an unauthenticated user was tricked into opening a crafted password reset link. The reporter states this did not affect authenticated user sessions; that disclaimer is reflected in the impact assessment here.
