Full Report
Multiple vulnerabilities have been discovered in Adobe products, the most severe of which could allow for arbitrary code execution.Adobe Campaign Classic is an enterprise-grade marketing automation platform that helps organizations design, automate, and track complex, personalized cross-channel marketing campaigns.Adobe ColdFusion is a commercial rapid web application development platform used to build and deploy dynamic web and mobile applications.Successful exploitation of the most severe of these vulnerabilities could allow for arbitrary code execution in the context of the logged on user. Depending on the privileges associated with the user, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.

- CVE-2026-48276, CVE-2026-48283 | CWE-434: Unrestricted Upload of File with Dangerous Type
- CVE-2026-48277, CVE-2026-48281, CVE-2026-48316, CVE-2026-48315 | CWE-20: Improper Input Validation
- CVE-2026-48282, CVE-2026-48313, CVE-2026-48314 | CWE-22: Path Traversal
- CVE-2026-48307 | CWE-79: Reflected Cross-site Scripting (XSS)
- CVE-2026-48285 | CWE-918: Server-Side Request Forgery (SSRF)
**Adobe Campaign Classic:**
- CVE-2026-48286 | CWE-285: Incorrect Authorization
## Affected Systems
- **Adobe Campaign Classic (ACC) v7:** Version 7.4.3 build 9396 and earlier.
- **Adobe ColdFusion 2025:** Update 9 and earlier versions.
- **Adobe ColdFusion 2023:** Update 20 and earlier versions.
## Vulnerability Description
The primary threat involves a suite of flaws allowing for **Arbitrary Code Execution (ACE)**.
- In **ColdFusion**, the most critical flaws involve the unrestricted upload of dangerous files and path traversal, which allow attackers to bypass directory restrictions or upload malicious scripts (webshells) to the server.
- In **Campaign Classic**, incorrect authorization checks could allow users to perform actions beyond their intended permissions.
- Combined, these flaws allow an attacker to execute commands in the security context of the logged-on user.
## Exploitation
- **Status:** Not exploited in the wild (as of July 1, 2026).
- **Complexity:** Medium (varies by specific CVE).
- **Attack Vector:** Network (Remote).
## Impact
- **Confidentiality:** High (Ability to view sensitive data).
- **Integrity:** High (Ability to change or delete data and create new accounts).
- **Availability:** High (Ability to install programs or disrupt services).
## Remediation
### Patches
Adobe has released updates to address these vulnerabilities. Administrators should update to the following (or newer) versions:
- **Adobe Campaign Classic:** Update to version 7.4.4 or higher.
- **Adobe ColdFusion 2025:** Apply Update 10 or higher.
- **Adobe ColdFusion 2023:** Apply Update 21 or higher.
### Workarounds
No specific configuration workarounds were provided. The primary mitigation is the application of security patches.
## Detection
- **Indicators of Compromise:** Monitor for unusual file uploads to ColdFusion directories, specifically web-accessible folders. Check for unauthorized administrative account creation.
- **Detection Methods:**
- Utilize SCAP-compliant vulnerability scanners (Safeguard 7.6).
- Monitor application logs for path traversal patterns (e.g., `../` sequences) and SSRF attempts.
- Conduct authenticated penetration testing (Safeguard 16.13).
