An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-20266 in the wild and no public exploit code.\n\nAffected product: Splunk AI Toolkit. 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-2026-20266/ (Markdown: https://insights.sbomify.com/CVE-2026-20266/index.md)","id":"CVE-2026-20266","markdown":"https://insights.sbomify.com/CVE-2026-20266/index.md","name":"CVE-2026-20266","record":{"aliases":["GHSA-vxp7-5w84-27pf"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Splunk AI Toolkit","requires_auth":"high_privilege","summary":"An admin user can execute arbitrary OS commands on the host via unsafe shell execution in the btool configuration helper.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"ai_toolkit","vendor":"splunk"}],"cvss":{"score":9.1,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"In Splunk AI Toolkit versions below 5.7.4, a user who holds the \"admin\" Splunk role could execute arbitrary OS commands on the host running the Splunk Enterprise instance.  \n\nThe vulnerability is possible because of an unsafe shell execution pattern in the btool configuration helper, which constructs OS command strings from dynamic parameters without disabling shell interpretation.","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":"OS Command Injection in the btool Configuration Helper in Splunk AI Toolkit","id":"CVE-2026-20266","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"command_injection","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Cisco IOS XE Software Security Hardening Release","id":"CVE-2026-20267"},"packages":[],"prev":{"headline":"Insecure Default Domain Allowlist in Splunk AI Toolkit","id":"CVE-2026-20265"},"products":["Splunk AI Toolkit"],"published":"2026-06-17","related":[{"cvss_score":8.8,"headline":"Deserialization in Splunk AI Toolkit","id":"CVE-2026-76395","kev_date_added":null,"published":"2026-08-19"},{"cvss_score":8.3,"headline":"Improper Privilege Management through Agent Run History in Splunk AI Toolkit","id":"CVE-2026-76391","kev_date_added":null,"published":"2026-08-19"},{"cvss_score":8.3,"headline":"Missing Authorization in Container and Connection Management through the REST API in Splunk AI Toolkit","id":"CVE-2026-76394","kev_date_added":null,"published":"2026-08-19"},{"cvss_score":8.1,"headline":"Improper Access Control in Experiment History through the REST API in Splunk AI Toolkit","id":"CVE-2026-76397","kev_date_added":null,"published":"2026-08-19"},{"cvss_score":8.1,"headline":"Incorrect Permission Assignment for Scheduled Searches in Splunk AI Toolkit","id":"CVE-2026-76399","kev_date_added":null,"published":"2026-08-19"},{"cvss_score":7.5,"headline":"Improper Access Control through Scheduled Searches in Splunk AI Toolkit","id":"CVE-2026-76396","kev_date_added":null,"published":"2026-08-19"}],"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":"total"},"state":"PUBLISHED","updated":"2026-06-17","vendors":["Splunk"]},"summary":"An admin user can execute arbitrary OS commands on the host via unsafe shell execution in the btool configuration helper.","url":"https://insights.sbomify.com/CVE-2026-20266/"}
