In many typical Express use cases, an unauthenticated remote attacker can place the attack payload in the query string of the URL that is used to visit the application, such as a[__proto__]=b&a[__proto__]&a[length]=100000000. The fix was backported to qs 6.9.7, 6.8.3, 6.7.3, 6.6.1, 6.5.3, 6.4.1, 6.3.3, and 6.2.4 (and therefore Express 4.17.3, which has \"deps: qs@6.9.7\" in its release description, is not vulnerable).\n\ud83d\udccf Published: 2022-11-26T00:00:00.000Z\n\ud83d\udccf Modified: 2025-04-29T13:56:42.673Z\n\ud83d\udd17 References:\n1. https://github.com/expressjs/express/releases/tag/4.17.3\n2. https://github.com/ljharb/qs/pull/428\n3. https://github.com/n8tz/CVE-2022-24999\n4. https://lists.debian.org/debian-lts-announce/2023/01/msg00039.html\n5. https://security.netapp.com/advisory/ntap-20230908-0005/", "creation_timestamp": "2025-04-29T14:11:41.000000Z"}
