CVE-2024-31303Network attack vector

Unwanted sheet duplication via missing nonce

Published Apr 12, 2024 · Updated Apr 28, 2026

Cross-site request forgery in Fetch Designs Sign-up Sheets 2.2.11.1 and earlier allows remote attackers to duplicate sheets. The copy-sheet action accepts a state-changing request without validating a WordPress nonce, so it performs the copy under the victim's session. Successful exploitation requires an authenticated administrator to follow a crafted request and creates an unwanted duplicate of an existing sheet.
