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 open-telemetry's 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 host files when Java injection is enabled and the instrumentation runs with elevated privileges. The flaw 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 0.4.0 through 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 the Java workload can exploit the injector's trust of the TMPDIR environment variable and unsafe file creation semantics to overwrite arbitrary files on the host filesystem. This can lead to integrity and availability impacts. The vulnerability is addressed in version 0.8.0.
Potential Impact
An attacker with local control over a Java workload can overwrite arbitrary files on the host system, potentially leading to denial of service or integrity compromise. The vulnerability requires elevated privileges for the instrumentation and Java injection enabled. Confidentiality is not impacted. The CVSS v3.1 score is 8.4 (High), reflecting local attack vector with low complexity, requiring privileges, no user interaction, and causing high impact on integrity and availability.
Mitigation Recommendations
Upgrade opentelemetry-ebpf-instrumentation to version 0.8.0 or later, where this vulnerability is fixed. Since no official patch or temporary fix is indicated beyond this version update, applying this upgrade is the recommended remediation. If upgrading immediately is not possible, consider disabling Java injection or running the instrumentation with least privileges to reduce risk.
