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-2026-40454 in the wild and no public exploit code.\n\nAffected product: Apache IoTDB C++ client. 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-2026-40454/ (Markdown: https://insights.sbomify.com/CVE-2026-40454/index.md)","id":"CVE-2026-40454","markdown":"https://insights.sbomify.com/CVE-2026-40454/index.md","name":"CVE-2026-40454","record":{"aliases":["GHSA-74ph-cx7x-v56m"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"IoTDB C++ client","requires_auth":"none","summary":"A malicious server can crash the Apache IoTDB C++ client by sending malformed data, causing a denial of service.","user_interaction":"not_required","vuln_class":"memory_corruption"},"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:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"},{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"Out-of-bounds Read, Improper Input Validation vulnerability in Apache IoTDB C++ client.\nOut-of-bounds reads in IoTDB C++ client TsBlock deserializer crash client\nprocess on malformed server data.\n\nThis issue affects Apache IoTDB C++ client: 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":"Memory corruption in Apache IoTDB C++ client","id":"CVE-2026-40454","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"SQL Injection in LMS","id":"CVE-2026-40455"},"packages":[],"prev":{"headline":"Apache Camel has an incomplete fix for CVE-2025-27636","id":"CVE-2026-40453"},"products":["Apache IoTDB C++ client"],"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":"A malicious server can crash the Apache IoTDB C++ client by sending malformed data, causing a denial of service.","url":"https://insights.sbomify.com/CVE-2026-40454/"}
