CVE-2026-48331 is a server-side request forgery vulnerability in Adobe Campaign Classic affecting v7 up to and including 7.4.3 build 9398 on Windows and Linux. The flaw can be exploited remotely over the network without authentication or user interaction. Successful exploitation causes the vulnerable Adobe Campaign Classic server to issue attacker-controlled requests to internal or otherwise unreachable resources. In affected environments, this can expose internal services, cloud metadata endpoints, and administrative interfaces that are not directly accessible from the outside. The vulnerability is associated with scope change and has been described as capable of resulting in privilege escalation; reporting also indicates it is among the most severe Adobe Campaign Classic flaws in this update set and may be leveraged toward arbitrary code execution in some scenarios.
