FKIE_CVE-2026-41469

Vulnerability from fkie_nvd - Published: 2026-04-22 19:17 - Updated: 2026-10-26 21:10
Severity
5.2 (Medium) - CVSS:3.1/AV:A/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N
Summary
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.
