Title
Moodle: xss via password reset link due to insufficient username escaping
Summary
A flaw was found in Moodle. Insufficient sanitization of username input on the password reset page allows a remote attacker to conduct a cross-site scripting (XSS) attack. By convincing an unauthenticated user to access a specially crafted password reset link, an attacker could execute arbitrary script in the victim's browser.
