Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-86843 in the wild and no public exploit code.\n\nAffected product: Apache Airflow Teradata provider. 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-2026-86843/ (Markdown: https://insights.sbomify.com/CVE-2026-86843/index.md)","id":"CVE-2026-86843","markdown":"https://insights.sbomify.com/CVE-2026-86843/index.md","name":"CVE-2026-86843","record":{"aliases":["GHSA-w623-968q-qp55"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","data_read","data_modify"],"network_reachable":"yes","non_default_config":true,"product_category":"Airflow Teradata provider","requires_auth":"low_privilege","summary":"Attackers can execute arbitrary SQL and redirect connections by triggering a vulnerable example DAG with unvalidated parameters in the Apache Airflow Teradata provider.","user_interaction":"not_required","vuln_class":"sql_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"apache-airflow-providers-teradata","vendor":"apache"}],"cvss":{"score":6.3,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-89","name":"Improper Neutralization of Special Elements used in an SQL Command"}],"description":"The Apache Airflow Teradata provider's compute-cluster example Dag declared every one of its Dag Params as unconstrained free text and templated them straight into the compute-cluster operators, which interpolate those values into Teradata DDL. A user who is permitted to trigger that Dag - a lower-trust role than the Dag author, and one that needs no Teradata credentials of its own - could therefore supply SQL fragments that execute under the connection the task runs as, and could additionally redirect the task at any other connection defined in the deployment, because the connection id was itself a free-text Param. Only deployments that run this example Dag, or a Dag copied from it, are affected; the provider's operator code is unchanged. Users of apache-airflow-providers-teradata are recommended to upgrade to version 3.7.0 or later, whose example constrains the Params to validated identifiers and a closed value set and removes connection selection and free-form option strings from trigger-time input. Upgrading does not change a Dag already copied from the example; users who copied it should apply the same constraints to their copy.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Apache Airflow Teradata provider: SQL injection via unvalidated Dag Params in the compute-cluster example Dag","id":"CVE-2026-86843","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"sql_injection","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Dpdk: dpdk: guest-triggered use-after-free and type confusion in vhost-crypto session cleanup","id":"CVE-2026-86845"},"packages":[],"prev":{"headline":"Real3D Flipbook Lite \u003c 5.4 - Author+ Content Deletion and Stored XSS via Global Settings Overwrite","id":"CVE-2026-86842"},"products":["Apache Airflow Teradata provider"],"published":"2026-09-29","related":[{"cvss_score":6.5,"headline":"Information disclosure in Apache Airflow Teradata provider","id":"CVE-2026-81862","kev_date_added":null,"published":"2026-09-29"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-09-29","vendors":["Apache Software Foundation"]},"summary":"Attackers can execute arbitrary SQL and redirect connections by triggering a vulnerable example DAG with unvalidated parameters in the Apache Airflow Teradata provider.","url":"https://insights.sbomify.com/CVE-2026-86843/"}
