CVE-2025-29868

Private Data Structure Returned From A Public Method vulnerability in Apache Answer.

This issue affects Apache Answer: through 1.4.2.

If a user uses an externally referenced image, when a user accesses this image, the provider of the image may obtain private information about the ip address of that accessing user. Users are recommended to upgrade to version 1.4.5, which fixes the issue. In the new version, administrators can set whether external content can be displayed.

Weakness

The product has a method that is declared public, but returns a reference to a private data structure, which could then be modified in unexpected ways.
