DescriptionCVE.org

Improper Neutralization of Argument Delimiters in a Command ('Argument Injection') vulnerability in Salesforce Marketing Cloud Engagement (CloudPagesUrl module) allows Web Services Protocol Manipulation. This issue affects Marketing Cloud Engagement: before January 21st, 2026.

Executive ViewAI

Why It Matters

A critical vulnerability in Salesforce Marketing Cloud Engagement allows attackers to manipulate web service protocols through argument injection, potentially enabling unauthorized access to customer data and marketing infrastructure. Organizations using Marketing Cloud Engagement's CloudPagesUrl module face immediate risk of compromise until patches are applied, affecting customer trust and regulatory compliance.

Business Impact: Severe

Compensating Controls

Deploy Web Application Firewall (WAF) rules to detect and block argument injection payloads targeting CloudPagesUrl endpoints; implement network segmentation isolating Marketing Cloud Engagement infrastructure; disable CloudPagesUrl functionality if operationally feasible; enforce strict input validation and rate limiting on affected APIs; implement multi-factor authentication for Marketing Cloud administrative access; maintain enhanced audit logging of all CloudPagesUrl interactions; establish real-time alerting for anomalous web service protocol usage patterns.
