How broadly exploitable is this vulnerability?

Exploitability depends on who can influence connector credential configurations. If only highly trusted operators can modify these settings, the practical risk is lower. In multi-tenant or automated environments where configuration control is looser or indirect, the exposure is significantly higher.

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

The attacker needs the ability to create or modify the credential JSON used by the BigQuery Sink connector. This can come from direct administrative access to Kafka Connect configurations, compromised configuration management pipelines, or any interface that allows tenants to supply their own connector credentials.

What is the safest general fix pattern?

The most robust fix is to disallow or strictly constrain credential_source.file and credential_source.url in user-controlled configurations, and to rely instead on centrally managed, pre-validated credential mechanisms (such as environment-based credentials or managed identities). Any remaining use of credential_source fields should be tightly validated against allowlists for both paths and domains.
