CVE-2026-44219
LowCVSS 3.7Exploitation Probability (EPSS)
Low risk23th percentile - higher than 23% of all known CVEs
Summary
ciguard, a static security auditor for CI/CD pipelines, in versions 0.6.0 through 0.8.1 calls json.loads on HTTP responses without a maximum-bytes cap. A hostile or compromised endoflife.date/OSV.dev server (or a successful MITM) could return a multi-GB response, exhausting the ciguard process's memory.
Risk Assessment
An attacker can cause memory exhaustion and crash the ciguard process, leading to denial of service in the CI/CD pipeline. This may disrupt build and deployment processes.
Recommendation
Update ciguard to version 0.8.2 or later. Consider limiting trust in external data sources within the pipeline.
Other vulnerabilities in ciguard
See all- CVE-2026-44220Low
ciguard is a static security auditor for CI/CD pipelines. From 0.8.0 to 0.8.1, the discover_pipeline_files() function in src/ciguard/discovery.py walks a directory tree following symlinks, with cycle protection via tracking visited resolved paths. An attacker who can plant a symlink in a scanned directory can cause discovery to walk into the symlink target and return paths to pipeline-shaped files outside the requested root. This vulnerability is fixed in 0.8.2.
- CVE-2026-44218Low
ciguard is a static security auditor for CI/CD pipelines. From 0.1.0 to 0.8.1, the published ghcr.io/jo-jo98/ciguard container image inherits the default root user because the Dockerfile lacks a USER directive. This vulnerability is fixed in 0.8.2.
Original NVD description (English source)
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.
