Renovate brace‑expansion can create unexpected strings
published 16 days ago
Summary
Renovate uses a helper library that can build any text that starts and ends with the same pieces you give it. This means an attacker could cause the tool to generate unwanted or misleading strings, potentially leading to incorrect actions or data. Update Renovate (or the library it uses) to the latest version that fixes the issue.
What to do
- Update cleanstart renovate to version 43.177.9-r2.
- Update cleanstart renovate to version 43.180.0-r2.
