The cookie authentication method in WordPress 2.5 relies on a hash of a concatenated string containing USERNAME and EXPIRY_TIME, which allows remote attackers to forge cookies by registering a username that results in the same concatenated string, as demonstrated by registering usernames beginning with "admin" to obtain administrator privileges, aka a "cryptographic splicing" issue. NOTE: this vulnerability exists because of an incomplete fix for CVE-2007-6013.

Security readout for executives and security teams

CVE-2008-1930 is an old WordPress 2.5 authentication flaw. A remote user could potentially create a specially chosen account name that lets them forge an authentication cookie and gain administrator-level access. This is most urgent for any still-running WordPress 2.5 instance or legacy restored copy. Exposure is limited to WordPress 2.5 as described in the source bundle. Risk is highest where the site is reachable by attackers and user registration is possible. The bundle does not identify other affected products or versions. Prioritize remediation if WordPress 2.5 is present. The business impact is potential site takeover, content tampering, and credential exposure, but the issue is legacy and only matters where affected versions remain deployed. Mitigation focus: Identify and retire any WordPress 2.5 installations.; Review the WordPress 2.5.1 vendor advisory and upgrade per vendor guidance.; Disable public user registration on any legacy instance pending remediation..
