SCA: security update for github.com/prebid/prebid-server/v4 (GHSA-4p3g-4hcj-wpvx)

critical Tenable Cloud Security Plugin ID 445452

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Prebid Server is an open-source solution for running real-time advertising auctions in the cloud. Prior to
 version 4.4.0, certain bidder adapters in Prebid Server interpolate user-supplied parameters into outbound
 request URLs without properly validating host and subdomain values, allowing crafted bid request
 parameters to cause server-side requests to unintended destinations and potentially expose internal
 network services or sensitive server endpoints. This issue is fixed in version 4.4.0. (CVE-2026-54735)

Solution

Update the github.com/prebid/prebid-server/v4 library and its related packages to version 4.4.0 or later.
