This could permit query parameter smuggling when a Go proxy forwards a parameter with an unparsable value. After fix, ReverseProxy sanitizes the query parameters in the forwarded query when the outbound request's Form field is set after the ReverseProxy. Director function returns, indicating that the proxy has parsed the query parameters. Proxies which do not parse query parameters continue to forward the original query parameters unchanged.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","score":7.5},"cwes":["CWE-444"],"references":["https://go.dev/cl/432976","https://go.dev/issue/54663","https://groups.google.com/g/golang-announce/c/xtuG5faxtaU","https://pkg.go.dev/vuln/GO-2022-1038","https://security.gentoo.org/glsa/202311-09"],"products":["golang:go"],"source":"nvd","synced_at":"2026-10-19T21:36:05.460296998+00:00"},"epss":{"cve":"CVE-2022-2880","score":0.01408,"percentile":0.72623,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GO-2022-1038","url":"https://osv.dev/vulnerability/GO-2022-1038","summary":"Incorrect sanitization of forwarded query parameters in net/http/httputil","modified":"2026-07-15T16:30:47.292256583Z","packages":[{"ecosystem":"Go","name":"stdlib","purl":"pkg:golang/stdlib","ranges":["<1.18.7",">=1.19.0-0 <1.19.2"],"fixed":["1.18.7","1.19.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
