This can lead to failures of authentication, routing, and other issues.\n\nThis vulnerability can be found in the bundled copy of the Node.JS HTTP parser used in the `NIOHTTP1` module.\n\n### Workarounds\n\nNo workaround is available, users must upgrade.\n\n### References\n\nhttps://nodejs.org/en/blog/vulnerability/february-2020-security-releases/#http-request-smuggling-using-malformed-transfer-encoding-header-critical-cve-2019-15605","published":"2023-05-18T17:29:43Z","modified":"2023-05-18T17:29:43Z","cvss":{"score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"SwiftURL","name":"github.com/apple/swift-nio","fixedVersion":"1.14.2"},{"ecosystem":"SwiftURL","name":"github.com/apple/swift-nio","fixedVersion":"2.13.1"}],"fix":{"url":"https://github.com/apple/swift-nio/pull/1387","label":"apple/swift-nio#1387"},"references":[{"type":"WEB","url":"https://github.com/apple/swift-nio/security/advisories/GHSA-mgc4-wqv7-4pxm"},{"type":"WEB","url":"https://github.com/apple/swift-nio/pull/1387"},{"type":"WEB","url":"https://github.com/apple/swift-nio/pull/1388"},{"type":"WEB","url":"https://github.com/apple/swift-nio/commit/8da5c5a4e6c5084c296b9f39dc54f00be146e0fa"},{"type":"WEB","url":"https://github.com/apple/swift-nio/commit/bfde40cac8eca25ce021552513b20ee23fc6e306"},{"type":"WEB","url":"https://github.com/apple/swift-nio/commit/df9390006bce7da1b6273f804d3acbbfdfcc6154"},{"type":"WEB","url":"https://github.com/apple/swift-nio/commit/f94b22b506e3557cb1b325534fa9bbcd39c90246"},{"type":"PACKAGE","url":"https://github.com/apple/swift-nio"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2023-05-18T17:29:43Z"}}
