CVE-2026-115425: OPNsense cross-site scripting in web interface

CVE-2026-115425 · Severity: info · Published 2026-10-26

OPNsense is an open-source firewall that manages network traffic and security policies through a web-based administrative interface. Multiple XSS vulnerabilities in versions 26.7.1_1 and earlier allow a low-privileged attacker to inject and execute malicious JavaScript code. An attacker can store malicious code to target all users including administrators, or craft links that execute code when clicked, potentially leading to account takeover, credential theft, or unauthorized configuration changes.

Technical details

Two XSS vulnerabilities affect the web management interface: a stored XSS in the Interfaces → Assignments Description field (CWE-79) that persists and executes for all users viewing the interface configuration, and a reflected XSS in Firewall: Log Files: Live View search functionality that executes when the Apply button is pressed (CWE-116). Both require low privilege access or user interaction; the stored variant affects even root-level administrators viewing the dashboard.
