Summary
A flaw was found in operator-foundry. GitHub Actions and reusable workflows within the component are referenced using mutable tags (e.g., `@v0`, `@v4`) instead of fixed commit SHAs.
This allows an attacker to potentially alter the code executed in the Continuous Integration (CI) pipeline through an upstream compromise or by re-pointing a tag, leading to unauthorized code execution or manipulation. Moderate impact.
Red Hat severity: Moderate — CVSS 4.2 (CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:L/A:N). Weakness: CWE-829.

Mitigation checklist
- To mitigate this issue, Konflux users should ensure that all `uses:` references within their GitHub Actions workflows for `operator-foundry` are explicitly pinned to a full 40-character commit SHA. This prevents silent code changes through mutable tags. For example, instead of `@v4`, use `actions/checkout@b4ffde65f46336ab88eb53be808477a3936bae11 # v4.1.1`. This is a configuration change within the GitHub Actions workflow files and does not require service restarts.
