Go to dashboardAdobe Campaign Classic has an OS command injection flaw in which special characters are not neutralized before being passed to a system command. A low-privileged attacker can run arbitrary code in the context of the current user, without user interaction.
Summary written from the sources below. Check the originals before acting.
First seen by InfraStack 2026-10-27 17:32 UTC. All times on this page are UTC.
Self-managed (on-premise and hybrid) Adobe Campaign Classic v7 servers on build 9402 or earlier are exposed to any authenticated low-privileged user, who can run OS commands as the Campaign service account over the network with no user interaction. Adobe-hosted instances are already remediated per Adobe's release notes. The specific vulnerable feature is not named by Adobe.
| Product | Ecosystem | Affected | Fixed in |
|---|---|---|---|
| Adobe Campaign Classic | vendor | ACC v7 <= 7.4.4 build 9402 | 7.4.4 build 9403 |
Check your Campaign Classic build number (console Help > About, or server build). 7.4.4 build 9402 and earlier is affected; build 9403 or later is fixed.
Update Adobe Campaign Classic v7 to 7.4.4 build 9403 or later (Windows, Linux), then restart the Campaign server (nlserver) to load the build; the fix is active by default once restarted.
