CVE-2026-41433 OpenTelemetry eBPF Instrumentation: Privileged Java agent injection allows arbitrary host file overwrite via untrusted TMPDIR

OpenTelemetry eBPF Instrumentation provides eBPF instrumentation based on the OpenTelemetry standard. From 0.4.0 to before 0.8.0, 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...

CVE-2026-41433

OpenTelemetry eBPF Instrumentation (OpenTelemetry OBI) has a local impact flaw in the Java agent injection path for versions 0.4.0–0.7.x (before 0.8.0). A compromised Java workload can cause arbitrary host file overwrites when Java injection is enabled and OBI runs with elevated privileges. The r...

OpenTelemetry eBPF Instrumentation: Privileged Java agent injection allows arbitrary host file overwrite via untrusted TMPDIR

Summary 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...
