RHSA-2026%3A0531 PUBLISHED CVSS 7.5 HIGH

A flaw was found in qs, a module used for parsing query strings. A remote attacker can exploit an improper input validation vulnerability by sending specially crafted HTTP requests that use bracket notation (e.g., `a[]=value`). This bypasses the `arrayLimit` option, which is designed to limit the size of parsed arrays and prevent resource exhaustion. Successful exploitation can lead to memory exhaustion, causing a Denial of Service (DoS) where the application crashes or becomes unresponsive, making the service unavailable to users.
