CVE-2025-62713Network attack vector

Pre-authentication command execution via reinitialization chain

Published Oct 23, 2025 · Updated Oct 23, 2025

Command injection in Kottster 3.2.0 through 3.3.1 allows remote attackers to execute system commands against development servers. The initApp action accepts repeat initialization to create a root account and JWT, after which installPackagesForDataSource passes unescaped package arguments to an OS command. The chain requires network access to a development-mode instance; production deployments are unaffected, while successful exploitation grants root administrative access and arbitrary command execution.
