CVE-2026-76197: Adobe Campaign Classic (ACC) Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability
CVE-2026-76197 affects Adobe Campaign Classic (ACC). The flaw is described as a command injection vulnerability.
What happened
CVE-2026-76197: Adobe Campaign Classic (ACC) is affected by an Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerabilit. Adobe Campaign Classic (ACC) is affected by an Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability that could result in arbitrary code execution in the context of the current user. A security weakness in Adobe Campaign Classic (ACC) is being tracked as CVE-2026-76197.
CVE-2026-76197 affects Adobe Campaign Classic (ACC). The reported consequence is code execution, meaning successful exploitation could make the affected application or process run attacker-controlled code. The flaw is described as a command injection vulnerability.
An attacker could exploit this vulnerability to execute arbitrary code. Command injection happens when untrusted input is interpreted as a system command. Successful exploitation can allow an attacker to make the affected system run commands that the application was never meant to execute.
Editorial note: this News Brief follows the available evidence and adds length only when additional facts or useful context are available. Where public reporting does not establish a specific victim sequence, CyberDeltaForce does not present one as fact.
What the reporting and advisory establish
Adobe Campaign Classic (ACC) is affected by an Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability that could result in arbitrary code execution in the context of the current user.
An attacker could exploit this vulnerability to execute arbitrary code.
Exploitation of this issue does not require user interaction.
A security weakness in Adobe Campaign Classic (ACC) is being tracked as CVE-2026-76197. The flaw is described as a command injection vulnerability. Command injection happens when untrusted input is interpreted as a system command. Successful exploitation can allow an attacker to make the affected system run commands that the application was never meant to execute. The reported consequence is code execution, meaning successful exploitation could make the affected application or process run attacker-controlled code. The description places that code execution in the context of the current user, so the practical impact depends partly on what that user account can access.
What this means for your environment
Move from the published facts to the technical path, exposure conditions and defensive decisions that matter in a real environment.
Attack & Exploitation Path
The sequence below shows how the vulnerability can be reached and what successful exploitation can produce. Each stage is labeled by evidence status.
Adobe Campaign Classic (ACC) is present and the vulnerable function or code path is reachable in normal application use.
attacker-controlled input or the relevant workflow reaches the command injection condition described in the advisory.
the command injection condition is triggered inside Adobe Campaign Classic (ACC), creating the security boundary failure described by the advisory.
successful exploitation can result in attacker-controlled code execution in the affected application or process.
the reported impact is tied to the current user context, so the attacker's effective access depends on that user's permissions.
Why this matters to you
CVE-2026-76197 matters because the practical risk is not the score alone — it is whether Adobe Campaign Classic (ACC) exists in your environment and whether the reported trigger or exposure path can reach it. The current severity is CRITICAL 10. No exploitation flag is currently present in the CDF data, but that does not remove the need to validate affected systems.
Does this deserve attention in my environment?
Check the conditions below against your use of Adobe Campaign Classic (ACC).
Select the conditions that are true in your environment. Leaving a condition unselected does not mean you are safe — it only means you have not marked it as applicable.
- Search endpoint, software and asset inventory for Adobe Campaign Classic (ACC).
- Confirm the vendor-recommended fixed version or mitigation and verify deployment, not just assignment, across affected assets.
- Review relevant endpoint, application, network or identity telemetry for activity associated with exploitation of the affected component.
- Track vendor and government guidance for any change in exploitation status while remediation is underway.
What remains unconfirmed
- Available reporting does not currently indicate exploitation, but that can change as vendor, government or threat-intelligence reporting develops.
