CVE-2024-48897Network attack vector

Authenticated RSS feed tampering via missing ownership checks

Published Nov 18, 2024 · Updated Nov 19, 2024

Improper authorization in Moodle LMS before 4.1.14 allows remote authenticated users to edit or delete RSS feeds they do not own. The RSS feed edit and delete handlers accept a feed identifier without verifying that the current user may modify the selected feed. A logged-in account with feed-management access can alter or remove another user's feed; versions 4.2.0 through 4.2.10, 4.3.0 through 4.3.7, and 4.4.0 through 4.4.3 are also affected.
