{"cve":"CVE-2026-49254","nvd":{"published":"2026-09-15T15:17:16.577","modified":"2026-09-30T17:51:56.193","status":"Deferred","description":"Dragonfly is an open source P2P-based file distribution and image acceleration system. Prior to 2.4.4, manager/router/router.go registers GET /api/v1/oauth and GET /api/v1/oauth/:id without jwt.MiddlewareFunc() or RBAC(), while manager/handlers/oauth.go returns models.Oauth records and manager/models/oauth.go exposes Oauth.ClientSecret as client_secret in JSON. When an administrator has configured a GitHub or Google OAuth provider, an unauthenticated network client can reach GetOauth or GetOauths, load the stored models.Oauth record, and obtain the provider's client secret, client identifier, and redirect URL. The earlier GHSA-j8hf-cp34-g4j7 remediation protected the /jobs group only and did not protect these OAuth GET handlers. Disclosure of client_secret can enable abuse of the configured identity-provider integration, subject to the provider's redirect URI restrictions. This issue is fixed in 2.4.4.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:P","score":2.9},"cvss_v3":null,"cwes":["CWE-200","CWE-306"],"references":["https://github.com/dragonflyoss/dragonfly/commit/20cb2f9cb6372d13c029779f427bdb5ede111183","https://github.com/dragonflyoss/dragonfly/releases/tag/v2.4.4","https://github.com/dragonflyoss/dragonfly/security/advisories/GHSA-4q9j-6299-gxmr"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:53:43.293028046+00:00"},"epss":{"cve":"CVE-2026-49254","score":0.0048,"percentile":0.41124,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-4q9j-6299-gxmr","url":"https://osv.dev/vulnerability/GHSA-4q9j-6299-gxmr","summary":"Dragonfly Manager OAuth provider client_secret disclosure via unauthenticated GET /api/v1/oauth","modified":"2026-07-07T16:11:14.472596198Z","packages":[{"ecosystem":"Go","name":"d7y.io/dragonfly/v2","purl":"pkg:golang/d7y.io/dragonfly/v2","ranges":["<2.4.4"],"fixed":["2.4.4"]}]},{"id":"GO-2026-5901","url":"https://osv.dev/vulnerability/GO-2026-5901","summary":"Dragonfly Manager OAuth provider client_secret disclosure via unauthenticated GET /api/v1/oauth in d7y.io/dragonfly","modified":"2026-07-07T16:00:30.371991975Z","packages":[{"ecosystem":"Go","name":"d7y.io/dragonfly/v2","purl":"pkg:golang/d7y.io/dragonfly/v2","ranges":["<2.4.4"],"fixed":["2.4.4"]}]}],"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).
