Security readout for executives and security teams

This issue affects WordPress installations before 3.9.2 when Multisite is enabled. A remote authenticated administrator could abuse avatar URL handling to inject script or HTML and potentially gain Super Admin privileges. It matters most where separate site administrators are not fully trusted. Exposure is limited to WordPress Multisite deployments running versions before 3.9.2. Single-site WordPress or updated installations are not identified as affected in the supplied sources. Treat as high priority only for legacy WordPress Multisite assets. The issue is old, but affected deployments could allow a site administrator to become Super Admin, changing business impact from website defacement to platform-level control. Mitigation focus: Upgrade WordPress to 3.9.2 or later.; Apply Debian DSA-3001 updates where WordPress is installed from Debian packages.; Prioritize Multisite environments with delegated or untrusted site administrators..
