An attacker could leverage this to cause a temporary denial-of-service… | ||
| CVE-2022-24999 | Hig | 0.43 | 7.5 | 0.15 | Nov 26, 2022 | 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.

| CVE-2017-1000048 | Hig | 0.42 | 7.5 | 0.02 | Jul 17, 2017 | the web framework using ljharb's qs module older than v6.3.2, v6.2.3, v6.1.2, and v6.0.4 is vulnerable to a DoS. A malicious user can send a evil request to cause the web framework crash. | ||
| CVE-2026-2391 | Low | 0.17 | 3.7 | 0.00 | Feb 12, 2026 | ### Summary The `arrayLimit` option in qs does not enforce limits for comma-separated values when `comma: true` is enabled, allowing attackers to cause denial-of-service via memory exhaustion. This is a bypass of the array limit enforcement, similar to the bracket notation… | ||
