VNX-GH-010 – All secrets passed to a reusable workflow

Overview

The called workflow receives every secret the caller can see, not just the ones it uses. A reusable workflow in another repository, or one pinned to a mutable ref, becomes a way to exfiltrate all of them.

Severity: Medium | Confidence: high | CWE: CWE-200, CWE-668 | Command: vulnetix gha workflows

Uses, when available: repo, to rate each finding against the repository’s own configuration.

Remediation

Pass only the secrets the called workflow declares under on.workflow_call.secrets, by name.

Scoring

CWSS vector at the rule’s default severity: CWSS:1.0/TI:H/AP:A/AL:A/IC:N/FC:LT/RP:N/RL:A/AV:I/AS:N/IN:A/SC:A/BI:H/DI:M/EX:L/EC:N/P:W. A finding whose severity the repository’s settings moved is scored at its adjusted severity.
