CVE-2022-45152

A blind Server-Side Request Forgery (SSRF) vulnerability was found in
Moodle. This flaw exists due to insufficient validation of user-supplied
input in LTI provider library. The library does not utilise Moodle’s
inbuilt cURL helper, which resulted in a blind SSRF risk. An attacker can
send a specially crafted HTTP request and trick the application to initiate
requests to arbitrary systems. This vulnerability allows a remote attacker
to perform SSRF attacks.
