    Published 2026-10-08

    High·CVSS 7.5 EPSS 0.87%

    When "Trailer" headers are sent by a client, the HTTP server internally uses the header values to populate the Request.Trailer map passed to the server handler. Because Request.Trailer is a map, each entry incurs memory overhead. For HTTP/2 servers, a malicious client can exploit...

16. CVE-2026-56866 HTTP/1 client connection desynchronization after CONNECT rejection in net/http

    Published 2026-10-08

    High·CVSS 7.5 EPSS 0.60%

    When http.Transport sends an HTTP/1 CONNECT request with a non-empty Request.Body, it writes the body directly to the connection without framing after the request headers. If the server rejects the CONNECT request with a non-2xx keep-alive response, Transport returns the connecti...

17. CVE-2026-97030 Recognize yield as regexp preceder keyword in html/template
