CVE-2026-22322

Stored Cross‑Site Scripting in Link Aggregation Name Handling

State: Published
Severity: 7.1 High
Published: Mar 18, 2026
Updated: Mar 18, 2026
Reserved: Jan 7, 2026

Description

A stored cross‑site scripting (XSS) vulnerability in the Link Aggregation configuration interface allows an unauthenticated remote attacker to create a trunk entry containing malicious HTML/JavaScript code. When the affected page is viewed, the injected script executes in the context of the victim’s browser, enabling unauthorized actions such as interface manipulation. The session cookie is secured by the httpOnly Flag. Therefore an attacker is not able to take over the session of an authenticated user.
