WordPress and WordPress MU before 2.8.1 exhibit different behavior for a failed login attempt depending on whether the user account exists, which allows remote attackers to enumerate valid usernames. NOTE: the vendor reportedly disputes the significance of this issue, indicating that the behavior exists for "user convenience."

Security readout for executives and security teams

This issue lets someone tell whether a WordPress username exists by observing different failed-login behavior. It does not by itself provide account access, but it can help attackers build targeted password-guessing or phishing campaigns against old WordPress or WordPress MU sites. Exposure is most likely on internet-facing, unmaintained WordPress or WordPress MU installations older than 2.8.1. Modern WordPress deployments are unlikely to be directly affected by this specific historical CVE unless legacy copies remain online. Low priority for current, supported WordPress estates. Raise priority if the organization still hosts legacy WordPress MU or pre-2.8.1 WordPress systems exposed to the internet. Mitigation focus: Inventory WordPress and WordPress MU installations and record exact versions.; Upgrade or retire any instance older than 2.8.1 using vendor or package guidance.; Check distribution advisories if using packaged WordPress builds..
