Description
Cloudron 9.1.7 and 9.2 contain a stored cross-site scripting (XSS) vulnerability in the Branding Footer feature. An authenticated administrator can store crafted HTML containing JavaScript event handlers in the Footer setting. The stored value is rendered without sufficient sanitization on the public login / OpenID interaction page and in the System Event Log, causing attacker-controlled JavaScript to execute in the Cloudron web origin when an affected page is viewed.
