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.","published_at":"2026-10-08T22:54:00.230000Z","last_modified_at":"2026-10-15T16:18:24.967000Z","cvss_v3_score":7.5,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","cvss_v3_severity":"HIGH","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-362"],"nvd_references":["https://go.dev/cl/847188","https://go.dev/cl/847313","https://go.dev/issue/81867","https://groups.google.com/g/golang-announce/c/U2fTuyDJznI","https://groups.google.com/g/golang-announce/c/ZPwCyRUuGBs","https://pkg.go.dev/vuln/GO-2026-6617"],"vuln_status":"Awaiting Analysis","trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-10-08T23:37:29.207599Z","updated_at":"2026-10-20T02:20:54.235708Z"},"effective_severity":"HIGH","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"N","value_label":"None"},{"metric":"I","name":"Integrity","value":"N","value_label":"None"},{"metric":"A","name":"Availability","value":"H","value_label":"High"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"golang.org-x-net","vendor_name":"golang.org/x/net","product_slug":"golang.org-x-net-http2","product_name":"golang.org/x/net/http2","version_start":"0","version_start_inclusive":true,"version_end":"0.60.0","version_end_inclusive":false,"cpe23_uri":"cve5:golang.org-x-net:golang.org-x-net-http2:0:0.60.0"},{"vendor_slug":"go-standard-library","vendor_name":"Go standard library","product_slug":"net-http","product_name":"net/http","version_start":"0","version_start_inclusive":true,"version_end":"1.26.9","version_end_inclusive":false,"cpe23_uri":"cve5:go-standard-library:net-http:0:1.26.9"},{"vendor_slug":"go-standard-library","vendor_name":"Go standard library","product_slug":"net-http-internal-http2","product_name":"net/http/internal/http2","version_start":"1.27.0-0","version_start_inclusive":true,"version_end":"1.27.2","version_end_inclusive":false,"cpe23_uri":"cve5:go-standard-library:net-http-internal-http2:1.27.0-0:1.27.2"}],"exploit_refs":[],"news":[],"references":[{"url":"https://go.dev/cl/847188","source_type":"MISC","tags":[]},{"url":"https://go.dev/cl/847313","source_type":"MISC","tags":[]},{"url":"https://go.dev/issue/81867","source_type":"MISC","tags":[]},{"url":"https://groups.google.com/g/golang-announce/c/U2fTuyDJznI","source_type":"MISC","tags":[]},{"url":"https://groups.google.com/g/golang-announce/c/ZPwCyRUuGBs","source_type":"MISC","tags":[]},{"url":"https://pkg.go.dev/vuln/GO-2026-6617","source_type":"MISC","tags":[]}],"timeline":[{"type":"published","at":"2026-10-08T22:54:00.230000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-10-15T22:02:21.122801Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-10-15T22:02:21.122801Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-10-15T22:02:21.122801Z","label":"CVSS score revised","source":"cvelistv5"}]}
