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.

Security readout for executives and security teams

This Moodle flaw lets a logged-in user read messages they should not be allowed to see. The issue affects older Moodle 2.1 and 2.2 releases. Business impact is mainly confidentiality: private user communications could be exposed to ordinary authenticated users. Exposure is limited to Moodle deployments running 2.1.x before 2.1.6 or 2.2.x before 2.2.3, where untrusted or broad user populations can authenticate. Public internet exposure increases privacy risk but authentication is still required. Treat as a privacy and trust issue for any legacy Moodle system. Prioritize remediation if the platform stores sensitive learner, staff, or institutional messages, especially where many users have accounts. Mitigation focus: Upgrade Moodle 2.1 deployments to 2.1.6 or later.; Upgrade Moodle 2.2 deployments to 2.2.3 or later.; If still running these branches, check current Moodle vendor guidance..
