Is this vulnerability remotely exploitable?

Yes, if the Scraparr `/metrics` endpoint is reachable from an attacker's network and the associated Readarr instance is also externally accessible, the attacker can retrieve the metrics output and obtain the API key.

What level of access does an attacker need to exploit this?

The attacker only needs HTTP access to the Scraparr `/metrics` endpoint; no authenticated access to Scraparr itself is required if the endpoint is exposed without protection.

What is the safest general fix pattern for similar issues?

Ensure that secrets are never used in telemetry fields (metrics labels, log messages, trace attributes) and are isolated to purpose-specific storage and transport mechanisms designed for confidential data. Use non-sensitive identifiers or aliases for anything that might be exported or widely visible.
