Security readout for executives and security teams
CVE-2009-3891 is an authenticated cross-site scripting issue in WordPress “Press This.” Sites running WordPress before 2.8.6 could let a logged-in user inject script or HTML through a selection parameter. Business impact is mainly account/session risk, content manipulation, and administrative trust erosion on very old WordPress installations. Exposure is limited to WordPress installations older than 2.8.6 where authenticated users can access wp-admin/press-this.php. Modern maintained WordPress versions should not be affected by this specific historical issue. Prioritize remediation if any internet-facing or multi-user WordPress site is still below 2.8.6. For current WordPress deployments, this is primarily a legacy hygiene issue rather than an emergency signal. Mitigation focus: Upgrade affected WordPress installations to 2.8.6 or a later supported release.; If immediate upgrade is impossible, review WordPress vendor guidance for temporary controls.; Restrict administrative access to trusted users until remediation is complete..
