### Impact Certain bidder adapters accept user-supplied parameters that are interpolated into outbound request URLs. Without proper input validation, a malicious actor could craft bid request parameters that cause the server to send HTTP requests to unintended destinations, potentially exposing internal network services or sensitive server endpoints to unauthorized access. ### Patches Patched in [v4.4.0](https://github.com/prebid/prebid-server/releases/tag/v4.4.0) ### Workarounds If one is unable to update, please make sure that the affected bidder adapters are disabled.
