It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-41433 exists.\n\nAffected packages and fixed versions:\n- go.opentelemetry.io/obi (Go): affected from 0.4.0; fixed in 0.8.0\n- go.opentelemetry.io/obi (Go): affected from 0.4.0; fixed in 0.8.0\n- go.opentelemetry.io/obi (Go): affected from 0.4.0; fixed in 0.8.0\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-41433/ (Markdown: https://insights.sbomify.com/CVE-2026-41433/index.md)","id":"CVE-2026-41433","markdown":"https://insights.sbomify.com/CVE-2026-41433/index.md","name":"CVE-2026-41433","record":{"aliases":["GHSA-8gmg-3w2q-65f4","GO-2026-5253"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_modify","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"OpenTelemetry eBPF instrumentation","requires_auth":"low_privilege","summary":"A local attacker can overwrite arbitrary host files via unsafe Java agent injection when OpenTelemetry eBPF instrumentation runs with elevated privileges.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"opentelemetry_ebpf_instrumentation","vendor":"opentelemetry"}],"cvss":{"score":8.4,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:N/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-59","name":"Improper Link Resolution Before File Access"},{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"OpenTelemetry eBPF Instrumentation provides eBPF instrumentation based on the OpenTelemetry standard.
