CVE-2025-40900 PUBLISHED

Angular template injection in Reports in Guardian/CMC before 26.1.0

Assigner: Nozomi
Reserved: 16.04.2025 Published: 19.05.2026 Updated: 19.05.2026

An Angular template injection vulnerability was discovered in the Reports functionality due to improper validation of an input parameter. An authenticated user with report privileges can define a malicious report containing an Angular template payload, or a victim can be socially engineered to import a malicious report template. When the victim views or imports the report, the Angular template executes in their browser context, allowing the attacker to modify application data, or disrupt application availability. Full XSS exploitation and direct information disclosure are prevented by the existing input validation and Content Security Policy configuration.
