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 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. This vulnerability is fixed in 0.8.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:N/I:H/A:H","score":8.4},"cwes":["CWE-22","CWE-59"],"references":["https://github.com/open-telemetry/opentelemetry-ebpf-instrumentation/releases/tag/v0.8.0","https://github.com/open-telemetry/opentelemetry-ebpf-instrumentation/security/advisories/GHSA-8gmg-3w2q-65f4","https://github.com/open-telemetry/opentelemetry-ebpf-instrumentation/security/advisories/GHSA-8gmg-3w2q-65f4"],"products":["opentelemetry:opentelemetry_ebpf_instrumentation"],"source":"nvd","synced_at":"2026-10-26T22:26:44.656832877+00:00"},"epss":{"cve":"CVE-2026-41433","score":0.00194,"percentile":0.09011,"date":"2026-10-26"},"kev":null,"osv":[{"id":"GHSA-8gmg-3w2q-65f4","url":"https://osv.dev/vulnerability/GHSA-8gmg-3w2q-65f4","summary":"OpenTelemetry eBPF Instrumentation: Privileged Java agent injection allows arbitrary host file overwrite via untrusted TMPDIR","modified":"2026-06-25T19:56:34.730575726Z","packages":[{"ecosystem":"Go","name":"go.opentelemetry.io/obi","purl":"pkg:golang/go.opentelemetry.io/obi","ranges":[">=0.4.0 <0.8.0"],"fixed":["0.8.0"]}]},{"id":"GO-2026-5253","url":"https://osv.dev/vulnerability/GO-2026-5253","summary":"OpenTelemetry eBPF Instrumentation: Privileged Java agent injection allows arbitrary host file overwrite via untrusted TMPDIR in go.opentelemetry.io/obi","modified":"2026-06-25T19:45:20.776420169Z","packages":[{"ecosystem":"Go","name":"go.opentelemetry.io/obi","purl":"pkg:golang/go.opentelemetry.io/obi","ranges":[">=0.4.0 <0.8.0"],"fixed":["0.8.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
