Heimdallr: Characterizing and Detecting LLM-Induced Security Risks in GitHub CI Workflows
Heimdallr systematically maps how LLM integrations in GitHub Actions create injectable attack surfaces via externally controllable inputs—a concrete and growing risk for any enterprise using AI-augmented CI/CD pipelines.

arXiv:2605.05969v2 Announce Type: replace Abstract: GitHub Continuous Integration (CI) workflows increasingly integrate Large Language Models (LLMs) to automate review, triage, content generation, and repository maintenance. This creates a new attack surface: externally controllable workflow inputs can shape LLM prompts and outputs, which may in turn affect security decisions, repository state, or privileged execution. Although LLM security and CI security have each been studied extensively, th
Editorial Analysis
As enterprises adopt LLM-powered automation in CI/CD, externally controllable workflow inputs become a new injection vector that traditional pipeline security controls may not cover.
Audit all GitHub Actions workflows that invoke LLM services for injection paths from untrusted external inputs and apply input sanitisation.
AI-augmented CI/CD pipelines introduce a new class of supply-chain injection risk that requires immediate workflow-level security review.
