An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-31039 in the wild and no public exploit code.\n\nAffected product: Apache bRPC. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2023-31039/ (Markdown: https://insights.sbomify.com/CVE-2023-31039/index.md)","id":"CVE-2023-31039","markdown":"https://insights.sbomify.com/CVE-2023-31039/index.md","name":"CVE-2023-31039","record":{"aliases":["GHSA-8fwm-xh4w-q393"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"Apache bRPC library","requires_auth":"none","summary":"Attackers can execute arbitrary code by influencing the pid_file parameter in Apache bRPC server options.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"brpc","vendor":"apache"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Security vulnerability in Apache bRPC \u003c1.5.0 on all platforms allows attackers to execute arbitrary code via ServerOptions::pid_file.\nAn attacker that can influence the ServerOptions pid_file parameter with which the bRPC server is started can execute arbitrary code with the permissions of the bRPC process.\n\nSolution:\n1. upgrade to bRPC \u003e= 1.5.0, download link:  https://dist.apache.org/repos/dist/release/brpc/1.5.0/ https://dist.apache.org/repos/dist/release/brpc/1.5.0/ \n2.
