{"id":"CVE-2023-31125","state":"PUBLISHED","title":"Uncaught exception in engine.io","description":"Engine.IO is the implementation of transport-based cross-browser/cross-device bi-directional communication layer for Socket.IO. An uncaught exception vulnerability was introduced in version 5.1.0 and included in version 4.1.0 of the `socket.io` parent package. Older versions are not impacted. A specially crafted HTTP request can trigger an uncaught exception on the Engine.IO server, thus killing the Node.js process. This impacts all the users of the `engine.io` package, including those who use depending packages like `socket.io`. This issue was fixed in version 6.4.2 of Engine.IO. There is no known workaround except upgrading to a safe version.","publishedAt":"2023-05-08T20:21:01.341Z","updatedAt":"2025-02-13T16:49:44.361Z","severity":{"score":6.5,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["socketio engine.io"],"affected":[{"vendor":"socketio","product":"engine.io","versions":[{"version":">= 5.1.0, < 6.4.2","status":"affected"}]}],"references":["https://github.com/socketio/engine.io/security/advisories/GHSA-q9mw-68c2-j6m5","https://github.com/socketio/engine.io/commit/fc480b4f305e16fe5972cf337d055e598372dc44","https://github.com/socketio/engine.io/releases/tag/6.4.2","https://security.netapp.com/advisory/ntap-20230622-0002/"],"weaknesses":["CWE-248"],"ingestedAt":"2026-10-29T20:06:00.499Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2023/31xxx/CVE-2023-31125.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2023-31125","state":"PUBLISHED","datePublished":"2023-05-08T20:21:01.341Z","dateUpdated":"2025-02-13T16:49:44.361Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2023-04-24T21:44:10.415Z"},"containers":{"cna":{"title":"Uncaught exception in engine.io","descriptions":[{"lang":"en","value":"Engine.IO is the implementation of transport-based cross-browser/cross-device bi-directional communication layer for Socket.IO.
