CVE-2025-29868Network attack vector

IP address disclosure via automatic external image loading

Published Apr 1, 2025 · Updated Apr 10, 2025

External image handling in Apache Answer 1.4.2 and earlier allows remote attackers to obtain visitors' IP addresses through browser requests. Rendered posts load externally referenced images automatically, causing each visitor's browser to contact the image provider rather than withholding the request. Exposure requires a visitor to open content containing an external image; the provider learns the visitor's source IP address but gains no reported access to Answer data.
