# CVE-2026-70382: Stored Cross-Site Scripting in Web Interface

Status: published. Published: 2026-10-26. Updated: 2026-11-02.

Some externally supplied values stored by the device may be rendered in the web interface without sufficient output encoding. An attacker who can influence one of these values could cause script execution in the browser of a user who views an affected page. Exploitation requires an attacker to influence a stored value and a user to view a page that renders it.

## Remediation

- workaround: Until an update can be applied, consider the following measures where operationally feasible:
  *  Restrict access to the web management interfaces on TCP ports 80 and 443 to trusted hosts only.


  *  Avoid opening or displaying content from untrusted sources on the device until it is updated.


WolfVision recommends keeping devices up to date and using dedicated, managed network segments (VLAN or firewall zone) to restrict device access to trusted hosts only. (source: CNA: ENISA)
