Phproject before 1.8.7 contains a missing object-level authorization vulnerability in the REST API issue endpoints (single_get, single_comments, single_comments_post) that allows authenticated API key holders to bypass the security.restrict_access confidentiality control by never invoking the allowAccess() authorization routine. Attackers can use a valid API key to read restricted issue contents and comments, including owner and author email addresses, and post unauthorized comments to issues they should not have access to.
