CVE-2026-88974
mediumWPGraphQL provides a GraphQL API for WordPress sites.
WPGraphQL provides a GraphQL API for WordPress sites. Prior to 2.22.2, the updatePost mutation in src/Mutation/PostObjectUpdate.php checks only the collection-level edit_posts capability and the post author, but does not enforce the object-level edit_post capability or require publish_posts for public status transitions. An authenticated Contributor can therefore publish the Contributor's own draft without editorial approval or modify the Contributor's previously published post despite lacking edit_published_posts, while posts owned by other authors remain protected. This issue is fixed in version 2.22.2.
