CVE-2025-27232

Super Admin file read via oauth.authorize action

Published Dec 1, 2025 · Updated Dec 1, 2025

Arbitrary file read in Zabbix Frontend 7.4.0 through 7.4.2 allows remote authenticated users to read webserver files via crafted HTTP requests. The oauth.authorize action processes the requests, but Zabbix has not published the affected parameter or the operation that permits attacker-directed file access. Exploitation requires a Super Admin account and exposes files readable by the frontend process, with no reported write or service-interruption impact.
