Summary
Exposure of Sensitive Information to an Unauthorized Actor vulnerability in Apache Answer.
This issue affects Apache Answer: through 2.0.0.
The unlisted question feature did not enforce access restrictions on direct API endpoints, allowing authenticated users to discover and access unlisted questions, their answers, comments, and revision history. Users are recommended to upgrade to version 2.0.1, which fixes the issue.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
