cicd-secrets-exfil
Extracting CI secrets / OIDC tokens once you have code execution in a build job — echo/printenv exfil, log-masking bypass (base64, char-split, reversal), OIDC token abuse to assume cloud roles, GITHUB_TOKEN / CI_JOB_TOKEN scope abuse, cache / artifact secret leakage, provenance pivot.

3 findings: 1 critical severity, 1 high severity, 1 medium severity. Installing this skill is not recommended: please review these findings carefully if you do intend to do so.
E006: Malicious code pattern detected in skill scripts.
What this means
Detected high-risk code patterns in the skill content — including its prompts, tool definitions, and resources — such as data exfiltration, backdoors, remote code execution, credential theft, system compromise, supply chain attacks, and obfuscation techniques.
Why it was flagged
This document contains step-by-step instructions to locate and exfiltrate CI secrets, bypass log masking, mint OIDC tokens and assume cloud roles, and persist access by pushing/signing artifacts — i.e., explicit guidance for credential theft, data exfiltration, remote takeover and supply-chain compromise.
W007: Insecure credential handling detected in skill instructions.
What this means
The skill handles credentials insecurely by requiring the agent to include secret values verbatim in its generated output. This exposes credentials in the agent’s context and conversation history, creating a risk of data exfiltration.
Why it was flagged
This skill instructs reading secrets from runner environment and shows commands that embed or print those secrets (headers, URLs, artifacts, DNS), i.e., it directs inclusion/exfiltration of secret values verbatim in commands and outputs.
W013: Attempt to modify system services in skill instructions.
What this means
The skill prompts the agent to compromise the security or integrity of the user’s machine by modifying system-level services or configurations, such as obtaining elevated privileges, altering startup scripts, or changing system-wide settings.
Why it was flagged
This skill explicitly instructs an agent to enumerate sensitive runner files and environment (including /proc), bypass log-masking, mint OIDC tokens and assume cloud roles, and push/sign artifacts — actions that exfiltrate credentials and mutate/persist state of the runner, repository, and cloud infrastructure.
