Why this deserves its current priority

CVSS is 8.5. Known-exploitation status makes exposure review time-sensitive. Treat this as a source-backed prioritization signal, not a statement about your environment.

Analysis status

Analysis pending evidence review

Factual feed record only; HOL analysis is not approved for indexing. Read the methodology.

Affected scope and exposure questions

The current feed maps Zammad GmbH/Zammad (generic), Zammad GmbH/Zammad (generic). Check affected ranges and fixed versions before updating.

Mapped affected packages and fixed versions

Recommended response

  1. 1Check inventory. Check lockfiles and deployed manifests for Zammad GmbH/Zammad, Zammad GmbH/Zammad.
  2. 2Review the reported fix. Update Zammad GmbH/Zammad to 7.2.2; Zammad GmbH/Zammad to 7.1.0-alpha if you use the affected versions. Test the change in a non-production environment first.

Upstream source description

Zammad packages built with packager.io (DEB and RPM) could have allowed a local attacker who already had file system write privileges as the unprivileged zammad service account to escalate to full root privileges on the host. Service processes began running as root and executed files that were owned and writable by the zammad account before dropping their identity to that account. An attacker holding that foothold could have escalated within seconds, because the affected services were restarted automatically whenever they stopped; no administrator interaction was required. Only installations from the DEB and RPM packages were affected — installations from source or the official container images were not. All released packaged versions were affected.
