Administrator-level script execution via unescaped Open Graph URL
Published Apr 22, 2025 · Updated May 12, 2026
Stored XSS in the Textmetrics WordPress plugin 3.6.2 and earlier allows remote authenticated users to execute scripts in visitors' browsers. The Open Graph image URL field stores attacker input that the plugin outputs without proper escaping, causing browsers to interpret it as script. Administrator-level access is required, and exposure is limited to multisite installations or sites with unfiltered_html disabled when another user opens the injected page.
