CVE-2026-44219

Description

ciguard is a static security auditor for CI/CD pipelines. From 0.6.0 to 0.8.1, both SCA HTTP clients (src/ciguard/analyzer/sca/osv.py and src/ciguard/analyzer/sca/endoflife.py) call payload = json.loads(resp.read().decode('utf-8')) without a maximum-bytes cap. A hostile or compromised endoflife.date / OSV.dev (or a successful TLS MITM) could return a multi-GB response, exhausting the ciguard process's memory. This vulnerability is fixed in 0.8.2.
