GHSA-F3PG-QWVG-P99C Lenient Parsing of Content-Length Header When Prefixed with Plus Sign

Summary hyper's HTTP/1 server code had a flaw that incorrectly parses and accepts requests with a Content-Length header with a prefixed plus sign, when it should have been rejected as illegal. This combined with an upstream HTTP proxy that doesn't parse such Content-Length headers, but forwards...

CVE-2021-32715

Hyper (Rust HTTP library) had a vulnerability in its HTTP/1 server code where a Content-Length header prefixed with a plus sign could be accepted instead of rejected, enabling potential request smuggling/desync attacks. The issue affects all prior Hyper versions before 0.14.10 when built with rus...
