CVE-2026-94440

Parsing a multipart form can bypass memory limits and read an arbitrarily long line into memory when the remaining limit at the start of a part is less than 400 bytes...

CVE-2026-78659 HTTP/2 server memory exhaustion due to Trailer headers in net/http

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 this by sending ...

CVE-2026-78659

An HTTP server is vulnerable to an asymmetric resource consumption attack via HTTP/2 "Trailer" headers. A malicious client can send a large number of fields within a "Trailer" header, forcing the server to allocate a disproportionate amount of memory because the Request.Trailer map incurs memory ...

CVE-2026-97031 Reject malformed ECH outer extension references in crypto/tls

Multiple ECH outer extension references are not permitted under RFC 9849; previously, a client could send a well-crafted packet that could trigger memory exhaustion in the server process by specifying multiple references. We now reject these as malformed and curb the memory amplification vector a...

CVE-2026-97031

A vulnerability exists in the Go programming language (or components using its network stack) where a client can send a well-crafted packet containing multiple ECH outer extension references , violating RFC 9849. This flaw allows an attacker to trigger memory exhaustion in the server process by s...
