The record
A flaw in the Java agent injection path allows a local attacker controlling a Java workload to overwrite arbitrary host files when Java injection is enabled and OBI is running with elevated privileges. The injector trusted `TMPDIR` from the target process and used unsafe file creation semantics, enabling both filesystem boundary escape and symlink-based file clobbering.
