Unauthenticated script execution in visitor browsers
Published Aug 13, 2026 · Updated Aug 13, 2026
Cross-site scripting in Lasso Analytics Lasso 358 and earlier allows remote attackers to execute scripts in visitors' browsers. Patchstack and the CNA record do not disclose the vulnerable parameter, request path, or code operation that accepts and renders attacker-controlled input. Successful exploitation requires a visitor to open the affected page, where injected script executes in that visitor's browser context.
