CVE-2026-63207: Zammad sensitive information exposure in integration API

CVE-2026-63207 · Severity: info · Published 2026-09-25

Zammad is an open source helpdesk and customer support system that manages support tickets and integrations with external services like LDAP and email systems. An authenticated administrator can retrieve stored integration credentials in plain text through the API instead of masked values, exposing passwords and secrets used to connect to critical backend systems. This could allow an administrator to compromise integrated email systems, directory services, and other connected infrastructure.

Technologies: Zammad. Vendors: Zammad.

Technical details

The integration administration API fails to consistently mask sensitive credential fields in responses for LDAP and Exchange integrations, returning plaintext secrets instead of masked placeholders. An authenticated administrator with access to the integration API can extract stored credentials. This requires administrative privileges and network access to the Zammad API; the vulnerability is fixed in version 7.1.2.
