Modern CI/CD pipelines are no longer passive delivery systems — they’ve become high-value attack surfaces where trust assumptions are routinely exploited. Incidents like the tj-actions GitHub Actions compromise show how mutable version tags can silently redirect trusted workflows into executing attacker-controlled code. Meanwhile, npm supply-chain worms such as Shai-Hulud demonstrate a more advanced threat: self-replicating malware that propagates through stolen publish tokens, harvesting credentials and reinfecting downstream systems without further human input. Across 2025–2026, the trend is clear: open-source ecosystems (npm, PyPI, GitHub Actions) are being hit by fast-moving, automation-driven attacks where compromise windows shrink from days to minutes. The result is a structural shift in security posture — where dependency integrity, token hygiene, and CI/CD hardening are no longer best practices, but survival requirements.
