Prior to 2.1.0, The Manager disables TLS certificate verification in HTTP clients. The clients are not configurable, so users have no way to re-enable the verification. A 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. This vulnerability is fixed in 2.1.0.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:L/SA:L/E:U","score":2.7},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:H","score":6.5},"cwes":["CWE-295"],"references":["https://github.com/dragonflyoss/dragonfly/blob/main/docs/security/dragonfly-comprehensive-report-2023.pdf","https://github.com/dragonflyoss/dragonfly/security/advisories/GHSA-98x5-jw98-6c97"],"products":["linuxfoundation:dragonfly"],"source":"nvd","synced_at":"2026-10-19T22:10:08.713834912+00:00"},"epss":{"cve":"CVE-2025-59347","score":0.0017,"percentile":0.06371,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-98x5-jw98-6c97","url":"https://osv.dev/vulnerability/GHSA-98x5-jw98-6c97","summary":"Dragonfly's manager makes requests to external endpoints with disabled TLS authentication","modified":"2025-09-26T16:16:47Z","packages":[{"ecosystem":"Go","name":"github.com/dragonflyoss/dragonfly","purl":"pkg:golang/github.com/dragonflyoss/dragonfly","ranges":["<2.1.0"],"fixed":["2.1.0"]},{"ecosystem":"Go","name":"d7y.io/dragonfly/v2","purl":"pkg:golang/d7y.io/dragonfly/v2","ranges":["<2.1.0"],"fixed":["2.1.0"]}]},{"id":"GO-2025-3966","url":"https://osv.dev/vulnerability/GO-2025-3966","summary":"Dragonfly's manager makes requests to external endpoints with disabled TLS authentication in d7y.io/dragonfly","modified":"2026-03-03T04:56:55.561219Z","packages":[{"ecosystem":"Go","name":"d7y.io/dragonfly/v2","purl":"pkg:golang/d7y.io/dragonfly/v2","ranges":["<2.1.0"],"fixed":["2.1.0"]},{"ecosystem":"Go","name":"github.com/dragonflyoss/dragonfly","purl":"pkg:golang/github.com/dragonflyoss/dragonfly","ranges":["all versions"],"fixed":[]}]}],"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).
