This can result in a nil dereference, and cause code to panic. The codebase may contain additional instances of the bug.\n\n```golang\nrequest, err := source.NewRequestWithContext(ctx, parentReq.Url,\nparentReq.UrlMeta.Header)\nif err != nil {\n log.Errorf(\"generate url [%v] request error: %v\", request.URL, err)\n span.RecordError(err)\n return err\n}\n```\n\nEve is a malicious actor operating a peer machine. She sends a dfdaemonv1.DownRequest request to her peer Alice. Alice’s machine receives the request, resolves a nil variable in the server.Download method, and panics.\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).","affected":[{"package":{"name":"github.com/dragonflyoss/dragonfly","ecosystem":"Go","purl":"pkg:golang/github.com/dragonflyoss/dragonfly"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2.1.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/09/GHSA-4mhv-8rh3-4ghw/GHSA-4mhv-8rh3-4ghw.json"}},{"package":{"name":"d7y.io/dragonfly/v2","ecosystem":"Go","purl":"pkg:golang/d7y.io/dragonfly/v2"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2.1.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/09/GHSA-4mhv-8rh3-4ghw/GHSA-4mhv-8rh3-4ghw.json"}}],"references":[{"type":"WEB","url":"https://github.com/dragonflyoss/dragonfly/security/advisories/GHSA-4mhv-8rh3-4ghw"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-59351"},{"type":"PACKAGE","url":"https://github.com/dragonflyoss/dragonfly"},{"type":"WEB","url":"https://github.com/dragonflyoss/dragonfly/blob/main/docs/security/dragonfly-comprehensive-report-2023.pdf"},{"type":"WEB","url":"https://pkg.go.dev/vuln/GO-2025-3970"}],"database_specific":{"cwe_ids":["CWE-476"],"github_reviewed":true,"github_reviewed_at":"2025-09-17T20:10:53Z","nvd_published_at":"2025-09-17T20:15:37Z","severity":"MODERATE"},"severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P"}]} |
