{"id":"CVE-2025-59347","aliases":["GHSA-98x5-jw98-6c97","GO-2025-3966"],"url":"https://o3.security/vulnerability/CVE-2025-59347","summary":"Dragonfly Manager makes requests to external endpoints with disabled TLS authentication","details":"### Impact\n\nThe Manager disables TLS certificate verification in two HTTP clients (figures 3.1 and 3.2). The clients are not configurable, so users have no way to re-enable the verification.\n\n```golang\nfunc getAuthToken(ctx context.Context, header http.Header) (string, error) { [skipped]\n       client := &http.Client{\n             Timeout: defaultHTTPRequesttimeout,\n             Transport: &http.Transport{\n                    TLSClientConfig: &tls.Config{InsecureSkipVerify: true},\n             },\n}\n[skipped]\n}\n```\n\nA Manager processes dozens of preheat jobs. An adversary performs a network-level Man-in-the-Middle attack, providing invalid data to the Manager. The Manager preheats with the wrong data, which later causes a denial of service and file integrity problems.\n\n### Patches\n\n- Dragonfy v2.1.0 and above.\n\n### Workarounds\n\nThere are no effective workarounds, beyond upgrading.\n\n### References\n\nA third party security audit was performed by Trail of Bits, you can see the [full report](https://github.com/dragonflyoss/dragonfly/blob/main/docs/security/dragonfly-comprehensive-report-2023.pdf).\n\nIf you have any questions or comments about this advisory, please email us at [dragonfly-maintainers@googlegroups.com](mailto:dragonfly-maintainers@googlegroups.com).","published":"2025-09-17T19:23:20.557Z","modified":"2026-08-12T03:51:13.965451049Z","cvss":null,"epss":{"score":0.0017,"percentile":0.06452,"asOf":"2026-08-24"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/dragonflyoss/dragonfly","fixedVersion":"2.1.0"},{"ecosystem":"Go","name":"d7y.io/dragonfly/v2","fixedVersion":"2.1.0"}],"fix":null,"references":[{"type":"WEB","url":"https://github.com/dragonflyoss/dragonfly/blob/main/docs/security/dragonfly-comprehensive-report-2023.pdf"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/59xxx/CVE-2025-59347.json"},{"type":"ADVISORY","url":"https://github.com/dragonflyoss/dragonfly/security/advisories/GHSA-98x5-jw98-6c97"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-59347"},{"type":"PACKAGE","url":"https://github.com/dragonflyoss/dragonfly"},{"type":"WEB","url":"https://pkg.go.dev/vuln/GO-2025-3966"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:13.965451049Z"}}
