Adobe Campaign Classic SQL Injection Leading to Remote Code Execution (CVE-2026-48330)

Technical Analysis

CVE-2026-48330 stems from improper neutralization of special elements in SQL commands within Adobe Campaign Classic, enabling classic SQL injection that escalates to arbitrary code execution in the context of the current application user. The 'Scope Changed' designation indicates the vulnerability allows attackers to impact resources beyond the vulnerable component itself, likely through underlying database server command execution or file system access via injected SQL payloads. Exploitation requires no user interaction and no authentication is explicitly mentioned as a prerequisite, making this a prime target for automated internet-wide scanning and exploitation once a PoC is released. Organizations often integrate Campaign Classic with customer databases, CRM systems, and increasingly with AI-driven marketing agents or LLM-based personalization pipelines that query campaign data via APIs; a compromise of this platform could expose customer PII, campaign credentials, or API keys that AI agents use to pull segmentation and personalization data, enabling downstream prompt injection or data poisoning in agentic marketing workflows. Given the CVSS 10.0 score, this should be treated as an emergency patching priority.

Affected Systems

Adobe Campaign Classic (ACC) - all versions prior to the vendor-issued patch; specific version ranges should be confirmed via the official Adobe Security Bulletin (APSB) associated with this CVE. Both on-premise and hybrid cloud deployments of Campaign Classic are presumed affected pending vendor confirmation.

Indicators of Compromise

• No specific IOCs published at time of disclosure.
• Monitor for anomalous SQL query patterns in Campaign Classic application logs.
• Watch for unexpected outbound connections from Campaign Classic application servers.
• Review database audit logs for unusual UNION-based or stacked SQL queries.

Remediation Steps

1. 1

   Apply Vendor Patch Immediately

   Monitor Adobe Security Bulletins (APSB) for the official patch addressing CVE-2026-48330 and apply it to all Campaign Classic instances as an emergency change.

2. 2

   Restrict Network Access

   Limit access to Campaign Classic administrative and API interfaces to trusted internal networks or VPN until patched.

3. 3

   Enable WAF Protections

   Deploy or update Web Application Firewall rules to detect and block SQL injection patterns targeting Campaign Classic endpoints.

4. 4

   Audit Database Access

   Review database logs for suspicious queries, unauthorized schema changes, or data exfiltration indicators dating back to disclosure.

5. 5

   Rotate Credentials and API Keys

   Rotate database credentials, service account passwords, and any API keys used by integrated systems, including AI agents or automation tools that query Campaign Classic data.

6. 6

   Implement Least Privilege

   Ensure the application's database user account operates with minimal necessary privileges to limit the impact of any future injection attempts.
