2021 also saw the disclosure and patching of a notable security vulnerability in jq . The official Ubuntu Security Notice , published on March 15, 2021, details the issue: it was discovered that jq did not perform sufficient bounds checking, resulting in a risk of unbounded resource consumption. An attacker could exploit this by providing a specially crafted JSON input, which would cause the application to crash in a Denial of Service (DoS) attack. While its CVSS score might be low due to local access requirements, for servers processing untrusted JSON data, this vulnerability posed a tangible risk to stability.
