CVE-2025-40900

Angular template injection in Reports in Guardian/CMC before 26.1.0

Published May 19, 2026 CVSS 4.0 · 5.1 Medium EPSS < 1% KEV · Not listed
Description
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.
