CVE-2026-102490 is an improper privilege management vulnerability in Zammad DEB and RPM packages built with packager.io. A local attacker with filesystem write privileges as the unprivileged zammad service account can modify files executed by service processes while they still run as root, before those processes drop privileges to the zammad account. Automatic service restarts permit escalation within seconds without administrator interaction. Source installations and official container images are unaffected. The vulnerability is described as affecting all released packaged versions; a later affected-product entry lists versions from 1.5.0 to before 7.2.2, while earlier records give inconsistent boundaries around 7.1.0-alpha.
