TL;DR

Affected versions of this package constructed API client URLs without wrapping runId (and similar path segments) in encodeURIComponent, allowing attackers to inject reserved characters (such as /, .., or ?) into these segments. This could lead to unintended routing or path traversal-like effects.

You are affected if you are using a version that falls within the vulnerable range.
