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-2026-40452 in the wild and no public exploit code.\n\nAffected product: Apache IoTDB. 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-2026-40452/ (Markdown: https://insights.sbomify.com/CVE-2026-40452/index.md)","id":"CVE-2026-40452","markdown":"https://insights.sbomify.com/CVE-2026-40452/index.md","name":"CVE-2026-40452","record":{"aliases":["GHSA-xxj7-h37p-p48c"],"analysis":{"component_type":"database","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache IoTDB","requires_auth":"none","summary":"Unauthorized authenticated users can access last-value data via the fastLastQuery endpoint due to missing authorization checks.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"},{"id":"CWE-284","name":"Improper Access Control"}],"description":"Incorrect Authorization, Improper Access Control vulnerability in Apache IoTDB.\nAuthorization bypass in /rest/v2/fastLastQuery exposes last-value data to unauthorized authenticated users.\n\nThis issue affects Apache IoTDB: from 1.3.5 before 1.3.8, from 2.0.5 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":"Missing authorization in Apache IoTDB","id":"CVE-2026-40452","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Apache Camel has an incomplete fix for CVE-2025-27636","id":"CVE-2026-40453"},"packages":[],"prev":{"headline":"Cross-site scripting in Chrome browser extension","id":"CVE-2026-40451"},"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":"partial"},"state":"PUBLISHED","updated":"2026-07-10","vendors":["Apache Software Foundation"]},"summary":"Unauthorized authenticated users can access last-value data via the fastLastQuery endpoint due to missing authorization checks.","url":"https://insights.sbomify.com/CVE-2026-40452/"}
