Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-20203 in the wild and no public exploit code.\n\nAffected product: Splunk Splunk. 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-2026-20203/ (Markdown: https://insights.sbomify.com/CVE-2026-20203/index.md)","id":"CVE-2026-20203","markdown":"https://insights.sbomify.com/CVE-2026-20203/index.md","name":"CVE-2026-20203","record":{"aliases":["GHSA-gpm4-vrgj-h7qc"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_modify","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Splunk Enterprise","requires_auth":"low_privilege","summary":"Low-privileged users can toggle Data Model Acceleration without required permissions, allowing unauthorized modification of system settings.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"splunk","vendor":"splunk"},{"product":"splunk_cloud_platform","vendor":"splunk"}],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"}],"description":"In Splunk Enterprise versions below 10.2.2, 10.0.5, 9.4.10, and 9.3.11, and Splunk Cloud Platform versions below 10.4.2603.0, 10.3.2512.6, 10.2.2510.10, 10.1.2507.19, 10.0.2503.13, and 9.3.2411.127, a low-privileged user that does not hold the `admin` or `power` Splunk roles, has write permission on the app, and does not hold the high-privilege capability `accelerate_datamodel`, could turn on or off Data Model Acceleration due to improper access control.","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":"Improper Access Control in Data Model Acceleration in Splunk Enterprise","id":"CVE-2026-20203","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"splunk:splunk","products":["splunk:splunk","splunk:splunk_cloud_platform"],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Improper Handling and Insufficient Isolation of Specific Temporary Files in Splunk Enterprise","id":"CVE-2026-20204"},"packages":[],"prev":{"headline":"Improper Input Validation during User Account Creation in Splunk Enterprise","id":"CVE-2026-20202"},"products":["Splunk Cloud Platform","Splunk Enterprise"],"published":"2026-04-15","related":[{"cvss_score":9.8,"headline":"Splunk Enterprise Missing Authentication for Critical Function","id":"CVE-2026-20253","kev_date_added":"2026-06-18","published":"2026-06-10"},{"cvss_score":9.8,"headline":"Missing Authentication for Critical Function in the Patroni REST API in Splunk Enterprise","id":"CVE-2026-76268","kev_date_added":null,"published":"2026-10-07"},{"cvss_score":9.8,"headline":"Improper Neutralization in Splunk Enterprise","id":"CVE-2026-76284","kev_date_added":null,"published":"2026-10-07"},{"cvss_score":9.8,"headline":"Improper Adherence to Coding Standards in Splunk Enterprise","id":"CVE-2026-76285","kev_date_added":null,"published":"2026-10-07"},{"cvss_score":9.8,"headline":"Auth bypass in n/a","id":"CVE-2017-17067","kev_date_added":null,"published":"2017-11-30"},{"cvss_score":9.8,"headline":"Information disclosure in n/a","id":"CVE-2016-10126","kev_date_added":null,"published":"2017-01-10"},{"cvss_score":9.4,"headline":"Improper Access Control through Embedded Report REST API Requests in Splunk Enterprise","id":"CVE-2026-76310","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":"partial"},"state":"PUBLISHED","updated":"2026-04-15","vendors":["Splunk"]},"summary":"Low-privileged users can toggle Data Model Acceleration without required permissions, allowing unauthorized modification of system settings.","url":"https://insights.sbomify.com/CVE-2026-20203/"}
