Stored script execution via unescaped client address

Published Sep 15, 2026 · Updated Sep 15, 2026

Stored XSS in the client details view in Bacularis 1.0.0 through 6.5.0 allows attackers to execute JavaScript via a crafted client address. The view renders a stored client address without output escaping, causing crafted content to be interpreted as JavaScript when the affected page is opened. Exploitation requires the value to be stored and the affected page to be viewed; the public advisory does not identify the privilege needed to set the field.
