Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Moodle (moodle/moodle on Packagist) is affected in the mod_data module's edit and delete pages, which expose the CSRF token in a GET parameter, in versions before 4.3.12, from 4.4.0-beta before 4.4.8, and from 4.5.0-beta before 4.5.4. The source says an attacker could see this token through the site's URL, which weakens protection against cross-site request forgery, but it gives few details on the conditions required. Upgrade to 4.3.12, 4.4.8, or 4.5.4, which are listed as fixed versions.
