Versions 0.56.0 and below are vulnerable to excessive memory allocation through quic-go's HTTP/3 client and server implementations by sending a QPACK-encoded HEADERS frame that decodes into a large header field section (many unique header names and/or large values). The implementation builds an http.Header (used on the http.Request and http.Response, respectively), while only enforcing limits on the size of the (QPACK-compressed) HEADERS frame, but not on the decoded header, leading to memory exhaustion. This issue is fixed in version 0.57.0."}], "lastModified": "2026-02-17T15:58:28.387", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:quic-go_project:quic-go:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "95E31549-EBE1-4F00-91C4-148BE3980FD0", "versionEndExcluding": "0.57.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
