Contributor-level post disclosure via unchecked get-posts handler
Published May 27, 2026 · Updated May 27, 2026
Missing authorization in The Post Grid 7.9.2 and earlier allows remote authenticated users to read posts through a Block CSS endpoint. BlocksController's get-posts handler returns requested post data without checking the caller's read_post capability. Contributor-level access is required, and the published impact is limited to unauthorized disclosure rather than modification or service interruption.
