{"cve":"CVE-2024-45410","nvd":{"published":"2024-09-19T23:15:11.480","modified":"2026-06-17T07:54:09.780","status":"Analyzed","description":"Traefik is a golang, Cloud Native Application Proxy. When a HTTP request is processed by Traefik, certain HTTP headers such as X-Forwarded-Host or X-Forwarded-Port are added by Traefik before the request is routed to the application. For a HTTP client, it should not be possible to remove or modify these headers. Since the application trusts the value of these headers, security implications might arise, if they can be modified. For HTTP/1.1, however, it was found that some of theses custom headers can indeed be removed and in certain cases manipulated. The attack relies on the HTTP/1.1 behavior, that headers can be defined as hop-by-hop via the HTTP Connection header. This issue has been addressed in release versions 2.11.9 and 3.1.3. Users are advised to upgrade. There are no known workarounds for this vulnerability.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","score":7.5},"cwes":["CWE-345","CWE-348"],"references":["https://github.com/traefik/traefik/releases/tag/v2.11.9","https://github.com/traefik/traefik/releases/tag/v3.1.3","https://github.com/traefik/traefik/security/advisories/GHSA-62c8-mh53-4cqv"],"products":["traefik:traefik"],"source":"nvd","synced_at":"2026-10-19T21:54:38.012257375+00:00"},"epss":{"cve":"CVE-2024-45410","score":0.01513,"percentile":0.7449,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-62c8-mh53-4cqv","url":"https://osv.dev/vulnerability/GHSA-62c8-mh53-4cqv","summary":"HTTP client can manipulate custom HTTP headers that are added by Traefik","modified":"2024-09-26T18:57:43.037863Z","packages":[{"ecosystem":"Go","name":"github.com/traefik/traefik/v3","purl":"pkg:golang/github.com/traefik/traefik/v3","ranges":[">=3.0.0-beta3 <3.1.3"],"fixed":["3.1.3"]},{"ecosystem":"Go","name":"github.com/traefik/traefik/v2","purl":"pkg:golang/github.com/traefik/traefik/v2","ranges":["<2.11.9"],"fixed":["2.11.9"]},{"ecosystem":"Go","name":"github.com/traefik/traefik","purl":"pkg:golang/github.com/traefik/traefik","ranges":["<2.11.9"],"fixed":["2.11.9"]}]},{"id":"GO-2024-3135","url":"https://osv.dev/vulnerability/GO-2024-3135","summary":"HTTP client can manipulate custom HTTP headers that are added by Traefik in github.com/traefik/traefik","modified":"2026-03-03T04:55:48.536445Z","packages":[{"ecosystem":"Go","name":"github.com/traefik/traefik","purl":"pkg:golang/github.com/traefik/traefik","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/traefik/traefik/v2","purl":"pkg:golang/github.com/traefik/traefik/v2","ranges":["<2.11.9"],"fixed":["2.11.9"]},{"ecosystem":"Go","name":"github.com/traefik/traefik/v3","purl":"pkg:golang/github.com/traefik/traefik/v3","ranges":[">=3.0.0-beta3 <3.1.3"],"fixed":["3.1.3"]}]}],"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).
