  "summary": "CVE-2022-24999 is fixed in 9 products on 1 platform, first by node-express 4.17.1-2ubuntu0.1~esm2, released November 26, 2022. It is not reported as exploited. Patch Radar priority: High.",
  "title": "node-express: qs before 6.10.3, as used in Express before 4.17.3 and other products, allows attackers to cause a Node process hang...",
  "description": "qs before 6.10.3, as used in Express before 4.17.3 and other products, allows attackers to cause a Node process hang for an Express application because an __ proto__ key can be used. 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\u0026amp;a[__proto__]\u0026amp;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 \u0022deps: qs@6.9.7\u0022 in its release description, is not vulnerable).",
