CVE-2022-45152Network attack vector

Unauthenticated blind SSRF via unvalidated LTI destinations

Published Nov 25, 2022 · Updated Apr 29, 2025

SSRF in Moodle LMS 4.0 through 4.0.4, 3.11 through 3.11.10, and 3.9.17 and earlier allows remote attackers to reach arbitrary systems. The LTI provider library sends user-supplied destinations without Moodle's inbuilt cURL helper, bypassing its destination validation. No authentication or user interaction is required; responses remain blind, but requests originate from the Moodle host's network context.
