CVE-2023-1979Network attack vector

Protected-story disclosure via read-only duplication check

Published May 8, 2023 · Updated Jan 28, 2025

Incorrect authorization in Google Web Stories for WordPress before 1.32 allows remote authenticated users to read protected story content. The REST create_item path accepted an original_id for duplication after checking only read permission, while the response returned story_data without enforcing the post password. An authenticated Author account and a password-protected story are required; successful exploitation discloses that story's protected content.
