Cache clearing via missing setup-action nonce
Published Jan 2, 2025 · Updated Apr 28, 2026
Cross-site request forgery in Extend Themes Mesmerize 1.6.120 and earlier allows remote attackers to clear the theme cache. The after_setup_theme action accepts a forged cache-clearing request without correctly validating a WordPress nonce. Exploitation requires a logged-in site administrator to follow a malicious link or submit a crafted form, causing an unwanted cache reset.
