Administrator-assisted settings modification via optional nonce check
Published Mar 31, 2026 · Updated Mar 31, 2026
Cross-site request forgery in Tim Eckel Minify HTML 2.1.12 and earlier allows remote attackers to alter settings through a forged request. The minify_html_menu_options function treats an absent minify_html_nonce field as acceptable and then writes submitted option values. Exploitation requires a logged-in site administrator to open an attacker-controlled link or page; the resulting changes can disrupt site rendering or behavior.
