PHP vulnerability analysis and mitigation
Overview
A vulnerability was discovered in Moodle (CVE-2025-3636) that allows unauthorized users to access and view RSS feeds due to insufficient capability checks. The vulnerability was disclosed on April 25, 2025, and affects Moodle versions 4.5 to 4.5.3, 4.4 to 4.4.7, 4.3 to 4.3.11, 4.1 to 4.1.17, and earlier unsupported versions (Wiz Security, NVD).
Technical details
The vulnerability is classified as CWE-639 (Authorization Bypass Through User-Controlled Key) and has been assigned a CVSS v3.1 base score of 4.3 (Medium) with the vector string CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N. The issue stems from inadequate permission checks in the Moodle RSS Block component, which fails to properly validate user capabilities before allowing access to RSS feeds (NVD, Wiz Security).
