{"cve":"CVE-2025-59350","nvd":{"published":"2025-09-17T20:15:37.373","modified":"2026-06-17T09:45:57.450","status":"Analyzed","description":"Dragonfly is an open source P2P-based file distribution and image acceleration system. Prior to 2.1.0, the access control mechanism for the Proxy feature uses simple string comparisons and is therefore vulnerable to timing attacks. An attacker may try to guess the password one character at a time by sending all possible characters to a vulnerable mechanism and measuring the comparison instruction’s execution times. 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:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U","score":2.7},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":5.3},"cwes":["CWE-208"],"references":["https://github.com/dragonflyoss/dragonfly/blob/main/docs/security/dragonfly-comprehensive-report-2023.pdf","https://github.com/dragonflyoss/dragonfly/security/advisories/GHSA-c2fc-9q9c-5486"],"products":["linuxfoundation:dragonfly"],"source":"nvd","synced_at":"2026-10-19T22:10:08.713834912+00:00"},"epss":{"cve":"CVE-2025-59350","score":0.00338,"percentile":0.27207,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-c2fc-9q9c-5486","url":"https://osv.dev/vulnerability/GHSA-c2fc-9q9c-5486","summary":"Dragonfly vulnerable to timing attacks against Proxy’s basic authentication","modified":"2025-09-26T16:17:59Z","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-2025-3972","url":"https://osv.dev/vulnerability/GO-2025-3972","summary":"Dragonfly vulnerable to timing attacks against Proxy’s basic authentication in d7y.io/dragonfly","modified":"2026-03-03T04:56:56.337510Z","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).
