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-2026-40008/ (Markdown: https://insights.sbomify.com/CVE-2026-40008/index.md)","id":"CVE-2026-40008","markdown":"https://insights.sbomify.com/CVE-2026-40008/index.md","name":"CVE-2026-40008","record":{"aliases":["GHSA-v4p4-86j5-2f8q"],"analysis":null,"analysis_generated_by":null,"assigner":"apache","cpe":[],"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-470","name":"Use of Externally-Controlled Input to Select Classes or Code"}],"description":"Use of Externally-Controlled Input to Select Classes or Code ('Unsafe Reflection') vulnerability in Apache IoTDB.\nThe pipe processor reads a fully\nqualified Java class name and\ninstantiates it using Class.forName().newInstance() without any\nvalidation or allowlisting.\n\nThis issue affects Apache IoTDB: from 1.0.0 before 2.0.10.\n\nUsers are recommended to upgrade to version 2.0.10, which fixes the issue.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Apache IoTDB: Arbitrary Class Instantiation via Pipe Transfer RPC","id":"CVE-2026-40008","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":null,"year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Apache IoTDB: Authenticated users can escalate to full tree-path access by renaming themselves to __internal_auditor","id":"CVE-2026-40009"},"packages":[],"prev":{"headline":"Denial of service in Apache IoTDB","id":"CVE-2026-40007"},"products":["Apache IoTDB"],"published":"2026-07-10","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-07-10","vendors":["Apache Software Foundation"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-40008/"}
