This happens because the server modifies the HPACK encoder from two goroutines without synchronization: one uses the encoder to encode a HEADERS frame as part of a response sent to a client and the other modifies the encoder's table size when handling a SETTINGS frame containing SETTINGS_HEADER_TABLE_SIZE that a client sends. A malicious client can repeatedly send a request while changing the header table size to crash the server.","state":0,"publishedAt":"2026-10-08T22:54:00.23+00:00","modifiedAt":"2026-10-15T15:46:39.417+00:00","affected":[{"ecosystem":"https://pkg.go.dev","name":"net/http","ranges":[],"versions":[],"rawVersionEvidence":"{\n

This happens because the server modifies the HPACK encoder from two goroutines without synchronization: one uses the encoder to encode a HEADERS frame as part of a response sent to a client and the other modifies the encoder's table size when handling a SETTINGS frame containing SETTINGS_HEADER_TABLE_SIZE that a client sends.
