mint: Content-Length header accepts non-RFC "+" sign prefix

Summary Mint's HTTP/1 client accepts Content-Length header values with a leading + sign e.g. +0, +123, which RFC 7230 forbids Content-Length = 1DIGIT. On a connection shared with a strict fronting proxy or load balancer, this parser disagreement is a response-smuggling primitive: the proxy frames...

GHSA-Q6GH-6V2R-HJV3 Micronaut: DefaultHttpClient follows redirects, forwarding Authorization, Cookie, and Proxy-Authorization headers

Impact DefaultHttpClient follows redirects and forwards Authorization, Cookie, and Proxy-Authorization headers to redirect targets across domain boundaries. The blocklist only filters Host/Connection/TE/CT/CL. Additionally, no maximum redirect count exists, enabling infinite loop DoS. Affected:...

GHSA-387M-935M-C4VW Micronaut doesn't set a maximum redirect count for its HTTP Client, enabling infinite loop DoS

The Netty-based Micronaut HTTP Client does not impose a limit on HTTP redirections, potentially allowing an infinite redirect loop that could lead to a denial-of-service attack.
