Persistent browser script execution via missing CSP
Published Apr 22, 2026 · Updated Apr 22, 2026
Missing CSP in Beghelli SicuroWeb version 0 allows man-in-the-middle attackers to load external scripts in operator browsers. SicuroWeb omits the CSP response header, so browsers permit dynamically created script elements to fetch code from attacker-controlled origins. Exploitation requires an adjacent network position and the companion template-injection and AngularJS sandbox-escape flaws; the chain persists its loader in localStorage and runs it in authenticated operator sessions.
