{"id":"GHSA-jpgg-cp2x-qrw3","summary":"Duplicate Advisory: ecnepsnai/web vulnerable to Uncontrolled Resource Consumption","details":"## Duplicate Advisory\nThis advisory has been withdrawn because it is a duplicate of GHSA-5gjg-jgh4-gppm. This link is maintained to preserve external references.\n\n## Original Description\nWeb Sockets do not execute any AuthenticateMethod methods which may be set, leading to a nil pointer dereference if the returned UserData pointer is assumed to be non-nil, or authentication bypass. This issue only affects WebSockets with an AuthenticateMethod hook. Request handlers that do not explicitly use WebSockets are not vulnerable.","aliases":["CVE-2021-4236","GHSA-5gjg-jgh4-gppm","GO-2021-0107"],"modified":"2026-01-23T22:52:14.943017Z","published":"2022-12-28T00:30:23Z","withdrawn":"2026-01-23T22:35:48Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2022-12-30T18:54:08Z","nvd_published_at":"2022-12-27T22:15:00Z","cwe_ids":["CWE-400","CWE-476"],"severity":"CRITICAL"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2021-4236"},{"type":"WEB","url":"https://github.com/ecnepsnai/web/commit/5a78f8d5c41ce60dcf9f61aaf47a7a8dc3e0002f"},{"type":"PACKAGE","url":"https://github.com/ecnepsnai/web"},{"type":"WEB","url":"https://pkg.go.dev/vuln/GO-2021-0107"}],"affected":[{"package":{"name":"github.com/ecnepsnai/web","ecosystem":"Go","purl":"pkg:golang/github.com/ecnepsnai/web"},"ranges":[{"type":"SEMVER","events":[{"introduced":"1.4.0"},{"fixed":"1.5.2"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/12/GHSA-jpgg-cp2x-qrw3/GHSA-jpgg-cp2x-qrw3.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
