Security readout for executives and security teams
Moodle 2.x and 3.x could allow text injection into email headers. The documented business impact is possible abuse of the Moodle server to send outbound spam, which can damage mail reputation and disrupt legitimate notifications. Organizations running legacy Moodle 2.x or 3.x with outbound email enabled are the likely exposure group. Exact vulnerable releases are not enumerated in the provided sources. Treat this as a reputation and operational-risk issue for legacy Moodle. Prioritize internet-facing or high-volume Moodle deployments that send email, especially where mail reputation affects business communications. Mitigation focus: Review Moodle advisory guidance for affected and fixed versions.; Upgrade unsupported Moodle 2.x or 3.x deployments where applicable.; Restrict Moodle mail relay permissions to required senders only..
