In syscall.StartProcess and os/exec.Cmd, invalid environment variable values containing NUL values are not properly checked for. A malicious environment variable value can exploit this behavior to set a value for a different environment variable. For example, the environment variable string \"A=B\\x00C=D\" sets the variables \"A=B\" and \"C=D\".","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":[],"references":["https://go.dev/cl/446916","https://go.dev/issue/56284","https://groups.google.com/g/golang-announce/c/mbHY1UY3BaM/m/hSpmRzk-AgAJ","https://pkg.go.dev/vuln/GO-2022-1095","https://go.dev/cl/446916"],"products":["golang:go"],"source":"nvd","synced_at":"2026-10-19T21:37:08.729216836+00:00"},"epss":{"cve":"CVE-2022-41716","score":0.01027,"percentile":0.63637,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GO-2022-1095","url":"https://osv.dev/vulnerability/GO-2022-1095","summary":"Unsanitized NUL in environment variables on Windows in syscall and os/exec","modified":"2026-02-04T04:25:45.960420Z","packages":[{"ecosystem":"Go","name":"stdlib","purl":"pkg:golang/stdlib","ranges":["<1.18.8",">=1.19.0-0 <1.19.3"],"fixed":["1.18.8","1.19.3"]}]}],"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).
