Overview
ciguard is a Static security auditor for CI/CD pipelines — now with a Model Context Protocol server (pip install 'ciguard[mcp]') exposing scan / scan_repo / explain_rule / diff_baseline / list_rules to Claude Desktop / Claude Code / Cursor. Plus .ciguardignore rationale-required suppression, baseline / delta reports, EOL-aware image checks, GitHub Actions CVE lookups across GitLab CI, GitHub Actions, and Jenkins Pipelines. Pre-commit hook + CIGUARD_MCP_DISABLED enterprise gate.
Affected versions of this package are vulnerable to Symlink Attack via the discover_pipeline_files function. An attacker can access files outside the intended directory by planting a symbolic link within a scanned directory, causing the process to follow the symlink and expose sensitive files from arbitrary locations.
