CLEANSTART-2026-DE25981: Using untrusted, non-normalized input as-is for metrics data (such as metric names, tag keys, or tag values) is a dangerous antipattern that general-purpose instrumentation should never perform

Q: What conditions are required for exploitation?

The issue is remotely reachable and requires no privileges or user interaction, but exploitation has high attack complexity. The provided data does not identify the specific input path or application workflow that an attacker would need to reach.

Q: What is the likely security impact?

The stated impact is integrity-only: integrity is rated high, while confidentiality and availability are rated none. The vulnerability concerns untrusted, non-normalized values used as metrics names, tag keys, or tag values.

Q: Are affected versions or a fixed version known?

No affected version range, fixed version, or patch information is provided. The data identifies the affected software as cleanstart/rundeck only.
