A specially crafted Socket.IO packet can trigger an uncaught exception on the Socket.IO server, thus killing the Node.js process. This issue is fixed by commit `15af22fc22` which has been included in `socket.io@4.6.2` (released in May 2023). The fix was backported in the 2.x branch as well with commit `d30630ba10`. Users are advised to upgrade. Users unable to upgrade may attach a listener for the \"error\" event to catch these errors.\n","state":0,"publishedAt":"2024-06-19T19:48:50.193+00:00","modifiedAt":"2024-09-03T20:35:40.515+00:00","affected":[{"ecosystem":"Vendor product","name":"socket.io","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"socketio\",\n                    \"product\": \"socket.io\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 2.5.1\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 3.0.0,< 4.6.2\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L","score":7.3,"severity":"HIGH"}],"references":["https://github.com/socketio/socket.io/security/advisories/GHSA-25hc-qcg6-38wj","https://github.com/socketio/socket.io/commit/15af22fc22bc6030fcead322c106f07640336115","https://github.com/socketio/socket.io/commit/d30630ba10562bf987f4d2b42440fc41a828119c"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2024-38355","license":"CVE Program Terms of Use","key":"cve-program:CVE-2024-38355","identifiers":["CVE-2024-38355"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
