Overview

Affected versions of this package are vulnerable to Symlink Attack via the findTempDir and copyAgent processes. An attacker can overwrite arbitrary files on the host system by controlling the TMPDIR environment variable in a Java process and leveraging symlink manipulation. This is only exploitable if Java agent injection is enabled, OBI is running with elevated privileges, and the attacker can run or control a Java process on the same host.
