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.","dates":{"published":"2026-06-23T15:32:36.000Z","modified":"2026-09-22T19:45:04.625Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":8.7,"severity":"high","version":"4.0","versionLabel":"v4.0","source":"OSV · Go","vector":"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","computed":true,"selection":"version-preference"},"metrics":[{"version":"4.0","versionLabel":"v4.0","source":"OSV · Go","score":8.7,"severity":"high","vector":"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","exploitability":null,"impact":null,"computed":true},{"version":"3.1","versionLabel":"v3.1","source":"OSV · Go","score":7.5,"severity":"high","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","exploitability":10,"impact":6,"computed":true}]},"epss":{"probability":null,"percentile":null,"severity":"unknown","asOf":null,"change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[],"last30":[]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[],"affected":[{"vendor":"github.com/traefik","product":"traefik","name":"github.com/traefik/traefik","label":"traefik","ecosystem":"Go","cpePart":null,"purl":"pkg:golang/github.com/traefik/traefik","purlType":"golang","versions":[{"text":"< 2.10.5","noFixRecorded":false,"fixedIn":null}],"versionsText":"< 2.10.5","eol":null,"hubHref":null}],"affectedCount":1,"eol":{"hasEol":false,"count":0},"references":[{"url":"https://github.com/traefik/traefik/security/advisories/GHSA-7v4p-328v-8v5g","label":"github.com/traefik/traefik/security/advisories/GHSA-7v4p-328v-8v5g","hostname":"github.com","tags":["WEB"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2023-54365","label":"nvd.nist.gov/vuln/detail/CVE-2023-54365","hostname":"nvd.nist.gov","tags":["Advisory"]},{"url":"https://access.redhat.com/security/cve/CVE-2023-54365","label":"access.redhat.com/security/cve/CVE-2023-54365","hostname":"access.redhat.com","tags":["WEB"]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2491710","label":"bugzilla.redhat.com/show_bug.cgi?id=2491710","hostname":"bugzilla.redhat.com","tags":["WEB"]},{"url":"https://security.access.redhat.com/data/csaf/v2/vex/2023/cve-2023-54365.json","label":"security.access.redhat.com/data/csaf/v2/vex/2023/cve-2023-54365.json","hostname":"security.access.redhat.com","tags":["WEB"]},{"url":"https://www.vulncheck.com/advisories/traefik-denial-of-service-via-http-2-request-handling","label":"www.vulncheck.com/advisories/traefik-denial-of-service-via-http-2-request-handling","hostname":"www.vulncheck.com","tags":["WEB"]}],"lineage":{"upstream":[],"downstream":["CVE-2023-54365"],"duplicates":[],"related":["CGA-CV8M-VXR5-MH4R"]},"timeline":[{"kind":"published","date":"2026-06-23T15:32:36.000Z","label":"Published","detail":"Vulnerability first disclosed.","source":null},{"kind":"modified","date":"2026-09-22T19:45:04.625Z","label":"Last modified","detail":"Vulnerability information updated.","source":null}],"risk":{"score":35,"level":"medium","profile":"Default","thresholds":{"critical":75,"high":50,"medium":25,"low":10}},"meta":{"dataAsOf":"2026-10-21T21:23:26.662Z","stale":false,"partial":false}}
