Security readout for executives and security teams
This issue exposes a WordPress post author’s username inside an HTML comment in page source. It does not directly grant access, but it can help attackers identify valid login names and target password attacks or social engineering. Exposure appears limited to public WordPress sites running WordPress 2.7.1 or serving vulnerable generated pages. Sites with public posts by privileged users have more meaningful exposure because disclosed usernames can support account targeting. Treat this as low urgency unless legacy WordPress 2.7.1 remains internet-facing. Prioritize confirming whether such systems exist, because the larger risk is obsolete software and account targeting rather than this disclosure alone. Mitigation focus: Check official WordPress guidance for the appropriate supported upgrade path.; Identify and retire any WordPress 2.7.1 deployments.; Review public templates and generated pages for leaked author usernames..
