Threats affecting pkg:pypi/ciguard

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.

The ciguard FastAPI Web UI lacked several HTTP defence-in-depth headers, including Content-Security-Policy, X-Frame-Options, and others, which were flagged by an OWASP ZAP scan. This absence reduces protection layers against attacks such as cross-site scripting (XSS), clickjacking, and risks from compromised third-party scripts. The issue is of minimal concern for local-only deployments but poses increased risk if the UI is publicly hosted. A patch introducing a SecurityHeadersMiddleware was released in version 0.8.2 to inject appropriate security headers, with regression tests added in 0.8.3.
