Information ExposureAffected versions of this package are vulnerable to Information Exposure in the BasicCookieStorage process, which does not enforce proper scoping rules for cookies as specified in RFC 6265. An attacker can access or receive cookies intended for other domains or schemes by leveraging a single storage instance across multiple origins or by sending Secure cookies over plain HTTP. This is only exploitable if a client uses the same storage instance for multiple origins or schemes.
How to fix Information Exposure? Upgrade org.http4k:http4k-core to version 4.51.0.0, 5.42.0.0, 6.48.0.0 or higher.

HTTP Request SmugglingAffected versions of this package are vulnerable to HTTP Request Smuggling in the reverseProxy process. An attacker can bypass routing-based authorization by sending a specially crafted Host header that matches a configured virtual host via substring, allowing unauthorized access to restricted routes. This is only exploitable if the deployment uses reverseProxy() or reverseProxyRouting() as a public-facing inbound HTTP handler with two or more configured virtual hosts.
How to fix HTTP Request Smuggling? Upgrade org.http4k:http4k-core to version 4.51.0.0, 5.42.0.0, 6.49.0.0 or higher.

Insufficient Verification of Data AuthenticityAffected versions of this package are vulnerable to Insufficient Verification of Data Authenticity through the misleadingly named HmacSha256.hash function. An attacker can bypass message authentication by exploiting the use of an unkeyed digest where a keyed HMAC was expected. This is only exploitable if downstream callers incorrectly assume HmacSha256.hash provides keyed authentication and use it for message authentication purposes.
How to fix Insufficient Verification of Data Authenticity? Upgrade org.http4k:http4k-core to version 6.49.0.0 or higher.
