CVE-2024-25979Network attack vector

Forum search URL pollution via unfiltered parameters

Published Feb 19, 2024 · Updated Aug 21, 2024

Improper parameter handling in Moodle LMS allows remote attackers to alter forum search URLs through unexpected query parameters. The forum search handler passed the complete request URL, including every supplied query parameter, to the page URL setter instead of constructing a URL from recognized fields. No authentication or user interaction is required; published sources describe no effect beyond allowing unrecognized parameters into the page URL.
