Executive Summary

This vulnerability in Apache Answer versions up to 2.0.0 involves improper authorization checks in timeline-related APIs.

Because of this flaw, regular authenticated users can access content that should be restricted, such as deleted, private, or unapproved content and its revision history.

The issue is fixed in version 2.0.1, which users are recommended to upgrade to.

Impact Analysis

This vulnerability can lead to unauthorized exposure of private or sensitive information to users who should not have access.

Such exposure could compromise confidentiality and privacy by allowing access to deleted, private, or unapproved content and its revision history.

Mitigation Strategies

To mitigate this vulnerability, users are recommended to upgrade Apache Answer to version 2.0.1, which contains the fix for the authorization issue.

Compliance Impact

This vulnerability involves exposure of private personal information to unauthorized actors due to an authorization bypass in Apache Answer's Timeline API. Such exposure can lead to non-compliance with data protection regulations like GDPR and HIPAA, which require strict controls over access to personal and sensitive information.

By allowing regular authenticated users to access deleted, private, or unapproved content and its revision history, the vulnerability increases the risk of unauthorized data disclosure, potentially violating privacy and security requirements mandated by these standards.

Upgrading to version 2.0.1, which fixes the issue, is recommended to restore compliance and reduce the risk of regulatory penalties.
