The Atlassian Questions For Confluence app for Confluence Server and Data Center creates a Confluence user account in the confluence-users group with the username disabledsystemuser and a hardcoded password. A remote, unauthenticated attacker with knowledge of the hardcoded password could exploit this to log into Confluence and access all content accessible to users in the confluence-users group. This user account is created when installing versions 2.7.34, 2.7.35, and 3.0.2 of the app.

The convertCommentToAnswer resource in Atlassian Confluence Questions before version 2.6.6, the bundled version of Confluence Questions was updated to a fixed version in Confluence version 6.9.0, allows remote attackers to modify a comment into an answer via a Cross-site request forgery (CSRF) vulnerability.
