CVE-2012-2354

Moodle 2.1.x before 2.1.6 and 2.2.x before 2.2.3 allows remote authenticated users to bypass the moodle/site:readallmessages capability requirement and read arbitrary messages by using the "Recent conversations" feature with a modified parameter in a URL.

Does this matter?

Lower severity and a low EPSS score (1.00%). Track it; it rarely justifies an emergency change on its own.
