Description
Zammad is a web based open source helpdesk/customer support system. Prior to 7.1.2, an authenticated user with agent permissions can supply an arbitrary AI analytics run identifier to the ticket summarize endpoint and receive the AI provider error message stored for that run, even if the run belongs to a ticket the agent is not authorized to access. The disclosure is limited to the provider error string; ticket content is not exposed. This issue is fixed in version 7.1.2.

AI Analysis

Impact

An authenticated user with agent permissions can specify any AI analytics run identifier when calling the ticket summarize endpoint. The response returns the error message stored by the AI provider for that run, even if the run belongs to a ticket the agent cannot access. The flaw arises from insufficient authorization checks (CWE‑639) and privilege escalation (CWE‑862). The only data exposed is the error string; the actual ticket content remains protected.

Affected Systems

The vulnerability is present in the Zammad helpdesk system. All versions prior to 7.1.2 are affected. Version 7.1.2 and later contain the fix introduced by the vendor.

Risk and Exploitability

The CVSS score of 2.3 classifies the issue as low severity. Because it requires authenticated agent access, the attack vector is internal and unlikely to be widely exploited. EPSS is not available, and the flaw is not listed in the CISA KEV catalog. The disclosed information is limited to an error string, making the overall impact modest but still worth addressing.

OpenCVE Recommended Actions

  • Upgrade Zammad to version 7.1.2 or later to apply the vendor‑supplied fix.
  • If an upgrade cannot be performed immediately, restrict agents' permissions to use the ticket summarize endpoint.
  • Ensure that role‑based access controls limit AI summarization to users who have legitimate access to the relevant ticket data.
