Unauthenticated code execution via OS command injection
Published Aug 25, 2026 · Updated Aug 29, 2026
OS command injection in Adobe Campaign Classic 7.4.4 build 9400 and earlier allows remote attackers to execute arbitrary code. Adobe has not disclosed the vulnerable input, request handler, or operation that passes attacker-controlled data into an OS command. No authentication or user interaction is required; successful exploitation runs commands with the privileges of the affected Campaign process.
