AI-suggested

A patch is available for this vulnerability. Users should upgrade Moodle to the fixed versions to prevent the HTTP authorization header from being preserved during redirects. No additional mitigation steps are indicated.

Description

Moodle's cURL wrapper retained the HTTP authorization header when following emulated redirects, potentially causing sensitive authorization information to be sent unintentionally to redirected URLs. This behavior affects multiple Moodle versions prior to their respective fixed releases. A patch is available to address this issue.
