CVE-2026-41433: CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in open-telemetry opentelemetry-ebpf-instrumentation
CVE-2026-41433 is a path traversal vulnerability in OpenTelemetry eBPF Instrumentation versions 0. 4. 0 up to but not including 0. 8. 0. It allows a local attacker controlling a Java workload to overwrite arbitrary files on the host when Java injection is enabled and the instrumentation runs with elevated privileges. The issue arises because the injector trusts the TMPDIR environment variable from the target process and uses unsafe file creation methods, enabling filesystem boundary escape and symlink-based file overwriting. This vulnerability is fixed in version 0. 8. 0.
AI Analysis
Technical Summary
OpenTelemetry eBPF Instrumentation versions from 0.4.0 to before 0.8.0 contain a path traversal vulnerability (CWE-22) in the Java agent injection path. When Java injection is enabled and the instrumentation runs with elevated privileges, a local attacker controlling a Java workload can exploit the injector's trust of the TMPDIR environment variable and unsafe file creation semantics to overwrite arbitrary host files. This can lead to integrity and availability impacts on the host system. The vulnerability is addressed in version 0.8.0.
Potential Impact
The vulnerability allows a local attacker with control over a Java workload to overwrite arbitrary files on the host system, potentially leading to denial of service or unauthorized modification of critical files. The CVSS score of 8.4 indicates high severity with impacts on integrity and availability. Confidentiality impact is not indicated. Exploitation requires local access and privileges to run Java workloads with injection enabled.
Mitigation Recommendations
This vulnerability is fixed in OpenTelemetry eBPF Instrumentation version 0.8.0. Users should upgrade to version 0.8.0 or later to remediate this issue. Since no official patch or temporary fix is indicated beyond upgrading, applying this update is the recommended mitigation.
