Cross-Site Scripting (XSS) in Auth0 AD/LDAP Connector (CVE-2026-85982)
Summary
Cross-site scripting in Auth0 AD/LDAP Connector (CVE-2026-85982). Successful exploitation can lead to full system takeover.
Original description
The description as published by the source.
The Auth0 AD/LDAP Connector is vulnerable to stored Cross-Site Scripting (XSS) issues due to improper HTML encoding of data in search results and updater log content displayed in the admin panel. An authenticated user with privileges to modify directory attributes, or a low-privileged local user on the host where the connector is installed, could insert script content. This script content could then execute in an administrator's browser when they view the affected search results or update logs.
