What it does
Comprehensive CI/CD pipeline exploitation methodology covering GitHub Actions injection vectors (expression injection via PR titles and issue bodies, workflow_run event abuse, GITHUB_TOKEN over-scoping, composite action supply chain compromise), Jenkins attack paths (Groovy sandbox escapes, script console remote code execution, Java remoting deserialization, credential store dumping, shared library injection), GitLab CI exploitation (YAML anchor injection, runner registration token abuse, CI variable extraction, protected branch bypass via merge request pipelines), and Azure DevOps pipeline agent compromise with service connection theft. Includes artifact poisoning techniques across all platforms, tooling guidance for gato and jenkins-attack-framework, and maps to MITRE ATT&CK T1195.002 (Supply Chain Compromise: Compromise Software Supply Chain). Covers enumeration of pipeline configurations, privilege escalation from contributor to code execution, lateral movement through pipeline trust boundaries, and persistence via modified workflow definitions. Each technique section provides working exploitation code, detection indicators, and defensive countermeasures.
Offensive CI/CD Pipeline Exploitation
CI/CD pipelines represent one of the highest-value targets in modern infrastructure. A compromised pipeline grants code execution in trusted contexts, access to deployment credentials, and the ability to inject malicious code into production artifacts. You exploit the implicit trust that organizations place in their build systems -- pipelines run code with elevated privileges, hold secrets for deployment, and operate with minimal monitoring compared to production systems.
This skill covers exploitation across the four dominant CI/CD platforms. You enumerate pipeline configurations, identify injection points, escalate from contributor-level access to arbitrary code execution, and leverage pipeline trust to move laterally through environments.

Quick Workflow
- Enumerate accessible repositories and their pipeline configurations (.github/workflows/, Jenkinsfile, .gitlab-ci.yml, azure-pipelines.yml).
- Identify the trigger model -- which events execute pipelines, and which contexts carry attacker-controlled input.
- Map token scopes and available secrets for each pipeline context.
- Select the injection vector matching your access level (contributor, external PR, authenticated user).
- Craft the payload for the target platform's expression language or script engine.
- Execute and capture output -- secrets, tokens, or artifact modification.
- Pivot using captured credentials to expand access to other pipelines, registries, or infrastructure.
GitHub Actions Expression Injection
GitHub Actions evaluates expressions in ${{ }} contexts. When attacker-controlled data flows into
these expressions without sanitization, you achieve arbitrary command injection in the runner context.
The most common injection surfaces are PR titles, issue bodies, branch names, and commit messages
that flow into run: steps or action inputs.
