Short explanation
CVE-2026-120317 is a missing integrity check vulnerability in http4k versions 4.9.10.0 through 6.60.0.0. The DigestEncoder computes the auth-int digest without hashing the request entity body, allowing on-path attackers on non-TLS channels to rewrite authenticated request bodies.
This vulnerability leads to a loss of integrity by allowing attackers to execute state-changing actions as the victim. On-path attackers on non-TLS channels can rewrite the request body while maintaining a valid Authorization header.
What should be done?
- Follow the vendor advisory to review necessary updates
- Upgrade affected http4k versions to 6.60.0.0 or an unaffected release
- Ensure TLS is enforced to secure network communications
Chain of evidence and sources
http4k 4.9.10.0 ile 6.60.0.0 sürümleri arasındaki yapı, auth-int özetini hesaplarken istek gövdesini hashlemez.
Yol üstü saldırganlar TLS kullanılmayan kanallarda istek gövdesini yeniden yazabilir ve yetkilendirmeyi koruyabilir.
Show the technical text from the sources
http4k from 4.9.10.0 before 6.60.0.0 contains a missing integrity check vulnerability because DigestEncoder computes the auth-int digest without hashing the request entity body. On-path attackers on non-TLS channels can rewrite the body of authenticated requests while keeping the Authorization header valid, executing state-changing actions as the victim.
