CVE-2026-76197 is a critical OS command injection vulnerability in Adobe Campaign Classic (ACC). Insufficient neutralization of externally influenced special elements in operating-system commands allows attacker-controlled input to be interpreted as commands by the underlying operating system. The flaw affects ACC v7 build 9400 and earlier, including fully on-premise deployments and on-premise components of hybrid deployments on Windows and Linux. It has a CVSS v3.1 score of 10.0 with vector AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H.
