{"id":"GHSA-pvrg-q6jw-42p7","summary":"Duplicate Advisory: Traefik vulnerable to HTTP/2 request causing denial of service ","details":"### Duplicate Advisory\nThis advisory has been withdrawn because it is a duplicate of GHSA-7v4p-328v-8v5g. This link is maintained to preserve external references.\n\n### Original DescriptionTraefik before 2.10.5 and 3.0.0-beta4 is affected by a denial-of-service vulnerability in HTTP/2 request handling inherited from the Go standard library's HTTP/2 implementation (CVE-2023-44487 / CVE-2023-39325, the 'Rapid Reset' technique). A remote attacker can rapidly create and cancel HTTP/2 streams to exhaust server resources and cause service unavailability.","modified":"2026-09-22T19:45:04.625344850Z","published":"2026-06-23T15:32:36Z","withdrawn":"2026-09-22T19:37:41Z","database_specific":{"cwe_ids":["CWE-400","CWE-770"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2026-09-22T19:37:41Z","nvd_published_at":"2026-06-23T13:16:30Z"},"references":[{"type":"WEB","url":"https://github.com/traefik/traefik/security/advisories/GHSA-7v4p-328v-8v5g"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-54365"},{"type":"WEB","url":"https://access.redhat.com/security/cve/CVE-2023-54365"},{"type":"WEB","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2491710"},{"type":"WEB","url":"https://security.access.redhat.com/data/csaf/v2/vex/2023/cve-2023-54365.json"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/traefik-denial-of-service-via-http-2-request-handling"}],"affected":[{"package":{"name":"github.com/traefik/traefik","ecosystem":"Go","purl":"pkg:golang/github.com/traefik/traefik"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"2.10.5"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/06/GHSA-pvrg-q6jw-42p7/GHSA-pvrg-q6jw-42p7.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
