Summary
Exposure of Private Personal Information to an Unauthorized Actor vulnerability in Apache Answer.
This issue affects Apache Answer: through 1.7.1.
An unauthenticated API endpoint incorrectly exposes full revision history for deleted content. This allows unauthorized user to retrieve restricted or sensitive information. Users are recommended to upgrade to version 2.0.0, which fixes the issue.
