This critical vulnerability could expose internal network services and sensitive endpoints to exploitation, posing significant risks to data integrity and confidentiality. Organizations using affected versions should prioritize upgrading to 3.43.0 or later to mitigate this severe security threat.

Original NVD Description
Prebid Server Java is the Java version of Prebid Server. Prior to 3.43.0, certain bidder adapters interpolate user-supplied parameters into outbound request URLs without using HttpUtil to validate the resulting domain or path segment. A malicious actor who can supply bid-request parameters can cause the server to send HTTP requests to unintended destinations, potentially reaching internal network services, metadata endpoints, or other sensitive server endpoints with the server's network access. This issue is fixed in version 3.43.0.
