AI Powered Q&A
What immediate steps should I take to mitigate this vulnerability?
To mitigate this vulnerability, upgrade Scraparr to version 3.0.2 or later where the issue is fixed.
Additionally, ensure that the /metrics endpoint is not accessible to external or unauthorized users.
If the Readarr scraping feature is enabled, consider disabling it or configuring an alias to avoid exposing the Readarr API key.
How can this vulnerability impact me? :
If you are using Scraparr with the Readarr integration enabled and the conditions for this vulnerability are met, an attacker could gain access to your Readarr API key. This could allow unauthorized access to your Readarr instance, potentially leading to data exposure or manipulation. The impact is significant because the API key is sensitive information that grants access to the Readarr service.
Can you explain this vulnerability to me?
This vulnerability affects Scraparr, a Prometheus Exporter for the *arr Suite, specifically versions from 3.0.0-beta to before 3.0.2. When the Readarr integration was enabled without an alias configured, the exporter exposed the configured Readarr API key as the alias metric label value. This means that if the /metrics endpoint was accessible to unauthorized or external users and the Readarr instance was externally accessible, the Readarr API key could be disclosed through the exported metrics data.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
