Information disclosure in Apache Answer 1.7.1 and earlier allows remote attackers to read deleted content through an unauthenticated revision API. The revision API returns full revision history for deleted content without enforcing the content access restrictions that apply after deletion. No account or user interaction is required, and exposure is limited to restricted or sensitive content retained in revision history.
