CVE-2025-27102

Type:
CWE-79 Cross-Site Scripting (XSS)

Description

Agate is central authentication server software for OBiBa epidemiology applications. Prior to version 3.3.0, when registering for an Agate account, arbitrary HTML code can be injected into a user's first and last name. This HTML is then rendered in the email sent to administrative users. The Agate service account sends this email and appears trustworthy, making this a significant risk for phishing attacks. Administrative users are impacted, as they can be targeted by unauthenticated users. Version 3.3.0 fixes the issue.
