jq JSON Processor Hash Table Collision Denial-of-Service Vulnerability (CVE-2026-40164)

A denial-of-service vulnerability exists in jq versions prior to commit 0c7d133c3c7e37c00b6d46b658a02244fdd3c784 due to the use of a hardcoded seed in MurmurHash3, enabling attackers to craft JSON objects that trigger hash collisions and cause excessive CPU consumption.
