Unauthorized action via missing nonce validation
Published Feb 25, 2025 · Updated Apr 28, 2026
CSRF in FS Code Booknetic 4.0.9 and earlier allows remote attackers to trigger an unauthorized action through a forged request. The affected function omits or incorrectly performs WordPress nonce validation before accepting the request, but public sources do not identify the function or resulting action. Exploitation requires a logged-in site administrator to open malicious content or submit a forged form; the established consequence is limited to an unspecified unwanted action.
