This PR contains the following updates:
1.27.3→1.27.4HTTP/1 server crash due to MaxBytesReader header race in net/http
CVE-2026-97054 / GO-2026-6859
More information
Details
For HTTP/1 servers, when MaxBytesReader's limit is exceeded, "Connection: close" header is automatically set without synchronization, which might race with another header being set explicitly in the server handler. As a result, an HTTP/1 server that utilizes MaxBytesReader or MaxBytesHandler can crash due to runtime panic if its handler reads the request body concurrently with writing the response header.
Severity
Unknown
