CVE-2026-48323Network attack vector

Unauthenticated code execution via template injection

Published Aug 3, 2026 · Updated Aug 3, 2026

Template injection in Adobe Campaign Classic 7.4.3 build 9398 and earlier allows remote attackers to execute arbitrary code. Adobe has not disclosed the affected template-processing component, input path, or the operation that fails to neutralize attacker-controlled template elements. Fully on-premise deployments and on-premise components of hybrid deployments are exposed over the network without authentication or user interaction, and successful exploitation runs code in the current process context.
