In versions prior to 0.49.0, 0.54.1, and 0.55.0, a misbehaving or malicious server can cause a denial-of-service (DoS) attack on the quic-go client by triggering an assertion failure, leading to a process crash. This requires no authentication and can be exploited during the handshake phase. This was observed in the wild with certain server implementations. quic-go needs to be able to handle misbehaving server implementations, including those that prematurely send a HANDSHAKE_DONE frame. Versions 0.49.0, 0.54.1, and 0.55.0 discard Initial keys when receiving a HANDSHAKE_DONE frame, thereby correctly handling premature HANDSHAKE_DONE frames.","state":0,"publishedAt":"2025-10-10T16:15:52.387+00:00","modifiedAt":"2026-10-19T16:10:00.26+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5,"severity":"HIGH"}],"references":["https://github.com/quic-go/quic-go/blob/v0.55.0/connection.go#L2682-L2685","https://github.com/quic-go/quic-go/pull/5354","https://github.com/quic-go/quic-go/security/advisories/GHSA-47m2-4cr7-mhcw"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2025-59530","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-617","CWE-755"],"productCriteria":[],"sourceDates":{"published":"2025-10-10T16:15:52.387","lastModified":"2026-10-19T16:10:00.260"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
