This makes it possible for authenticated attackers, with administrator-level access and above, to extract complete logged mail rows belonging to other users — including recipient addresses, message subjects, full message bodies, and any URLs contained therein — whose addresses happen to match the wildcard. Exploitation requires an administrator to process a personal-data export request for the attacker's email address via the standard WordPress privacy workflow, and the attacker's address must contain a LIKE wildcard character (such as an underscore) that matches at least one other user's address in the mail log.\n\n## Affected\n\n- `wp_mail_logging <= 1.17.0`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":15,"depthScoreParts":{"impact":14.9,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
