CVE-2026-127212 (CVSS 4.3)

Description

Dokploy before 0.31.1 contains a missing ownership check vulnerability in the readAppMonitoring tRPC procedure that allows authenticated attackers to access container metrics belonging to other organizations by supplying an arbitrary appName. Attackers can query getApplicationStats with any application name, including the fixed "dokploy" control-plane service name, to read CPU, memory, network I/O, and block I/O metrics for containers they do not own on self-hosted multi-tenant instances.
