AI-suggested

Upgrade Apache Answer to version 2.0.1 or later, where the access control issue for unlisted question API endpoints is fixed. Since a patch is available, applying this official fix is the recommended remediation.

Description

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.
