AI-suggested

Upgrade the Sign-up Sheets plugin to version 2.4.0 or later, where the CSRF nonce validation issue has been addressed. No other mitigation guidance is provided. Patch status is not explicitly confirmed by a vendor advisory, but the version 2.4.0 indicates the fix.

Description

The Sign-up Sheets WordPress plugin before 2.4.0 does not properly validate the CSRF nonce that protects its sign-up deletion action, allowing attackers to delete sign-up records via a forged request handled in the session of a logged-in user with the required capability.
