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.\n\n## Affected packages\n\n- `github.com/traefik/traefik < 2.10.5`\n\n## Remediation\n\nUpgrade to a patched release:\n\n- `github.com/traefik/traefik 2.10.5`","depth":"twilight","depthScore":41,"depthScoreParts":{"impact":41.3,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
