Summary
A flaw was found in qs. An unauthenticated attacker can exploit this by sending a specially crafted query string to an application using `qs.parse` with specific non-default settings (`comma: true` and `throwOnLimitExceeded: true`).
This bypasses a configured array limit, causing the parser to allocate an excessively large array. This can lead to a Denial of Service (DoS) by consuming too much memory.
Red Hat severity: Low — CVSS 3.7 (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L). Weakness: CWE-770.
Affected products named by the advisory: Cost Management On Premise; Cryostat 4; Gatekeeper 3; Migration Toolkit for Applications 8; and 47 more.
