## Description

The WPGraphQL plugin for WordPress is vulnerable to Sensitive Information Exposure via the updateComment and deleteComment mutations in all versions up to, and including, 2.24.1, due to a nonexistent comment ID returning a different error message than an existing comment the caller is not allowed to modify. This makes it possible for authenticated attackers with Subscriber-level access and above to enumerate which comment IDs exist, including unapproved comments.
