Vulnerability from github – Published: 2026-04-22 21:32 – Updated: 2026-04-22 21:32

Details

Beghelli Sicuro24 SicuroWeb does not enforce a Content Security Policy, allowing unrestricted loading of external JavaScript resources from attacker-controlled origins. When chained with the template injection and sandbox escape vulnerabilities present in the same application, the absence of CSP removes the browser-enforced restriction that would otherwise block external script execution, enabling attackers to load arbitrary remote payloads into operator browser sessions.

Severity ?
