Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-20166 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-2026-20166/ (Markdown: https://insights.sbomify.com/CVE-2026-20166/index.md)","id":"CVE-2026-20166","markdown":"https://insights.sbomify.com/CVE-2026-20166/index.md","name":"CVE-2026-20166","record":{"aliases":["GHSA-phr8-q335-28xj"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Splunk Enterprise","requires_auth":"low_privilege","summary":"Low-privileged users can retrieve sensitive API access tokens from the Discover Splunk Observability Cloud app due to improper access control.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"splunk","vendor":"splunk"},{"product":"splunk_cloud_platform","vendor":"splunk"}],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"In Splunk Enterprise versions below 10.2.1 and 10.0.4, and Splunk Cloud Platform versions below 10.2.2510.5, 10.1.2507.16, and 10.0.2503.12, a low-privileged user that does not hold the \"admin\" or \"power\" Splunk roles could retrieve the Observability Cloud API access token through the Discover Splunk Observability Cloud app due to improper access control. \n\nThis vulnerability does not affect Splunk Enterprise versions below 9.4.9 and 9.3.10 because the Discover Splunk Observability Cloud app does not come with Splunk Enterprise.","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":"Sensitive Information Disclosure in Discover Splunk Observability Cloud app for Splunk Enterprise","id":"CVE-2026-20166","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"splunk:splunk","products":["splunk:splunk","splunk:splunk_cloud_platform"],"type":"information_disclosure","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Cisco IoT Field Network Director Remote Device Denial of Service Vulnerability","id":"CVE-2026-20167"},"packages":[],"prev":{"headline":"Sensitive Information Disclosure in MongoClient logging channel in Splunk Enterprise","id":"CVE-2026-20165"},"products":["Splunk Cloud Platform","Splunk Enterprise"],"published":"2026-03-11","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":"2026-03-12","vendors":["Splunk"]},"summary":"Low-privileged users can retrieve sensitive API access tokens from the Discover Splunk Observability Cloud app due to improper access control.","url":"https://insights.sbomify.com/CVE-2026-20166/"}
