This mishandling could leave a client connection in an invalid state, where the next request sent on the connection will fail. An attacker sending a request to a net/http/httputil.ReverseProxy proxy can exploit this mishandling to cause a denial of service by sending \"Expect: 100-continue\" requests which elicit a non-informational response from the backend. Each such request leaves the proxy with an invalid connection, and causes one subsequent request using that connection to fail.","published_at":"2024-07-02T21:28:25.677000Z","last_modified_at":null,"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":"none","ssvc_automatable":true,"ssvc_technical_impact":"partial","cwes":null,"nvd_references":["https://go.dev/cl/591255","https://go.dev/issue/67555","https://groups.google.com/g/golang-dev/c/t0rK-qHBqzY/m/6MMoAZkMAgAJ","https://pkg.go.dev/vuln/GO-2024-2963"],"vuln_status":null,"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":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-29T01:53:22.351451Z"},"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":"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":"1.21.12","version_end_inclusive":false,"cpe23_uri":"cve5:go-standard-library:net-http:0:1.21.12"},{"vendor_slug":"go-standard-library","vendor_name":"Go standard library","product_slug":"net-http","product_name":"net/http","version_start":"1.22.0-0","version_start_inclusive":true,"version_end":"1.22.5","version_end_inclusive":false,"cpe23_uri":"cve5:go-standard-library:net-http:1.22.0-0:1.22.5"}],"exploit_refs":[],"news":[],"references":[{"url":"https://go.dev/cl/591255","source_type":"MISC","tags":[]},{"url":"https://go.dev/issue/67555","source_type":"MISC","tags":[]},{"url":"https://groups.google.com/g/golang-dev/c/t0rK-qHBqzY/m/6MMoAZkMAgAJ","source_type":"MISC","tags":[]},{"url":"https://pkg.go.dev/vuln/GO-2024-2963","source_type":"MISC","tags":[]}],"timeline":[{"type":"published","at":"2024-07-02T21:28:25.677000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:34:21.408179Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:34:21.408179Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:34:21.408179Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"ssvc_changed","at":"2026-06-29T01:53:22.351451Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-06-29T01:53:22.351451Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-06-29T01:53:22.351451Z","label":"SSVC decision revised","source":"vulnrichment"}]}
