Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-20381 in the wild and no public exploit code.\n\nAffected product: Splunk MCP Server. 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-2025-20381/ (Markdown: https://insights.sbomify.com/CVE-2025-20381/index.md)","id":"CVE-2025-20381","markdown":"https://insights.sbomify.com/CVE-2025-20381/index.md","name":"CVE-2025-20381","record":{"aliases":["GHSA-qf9v-6rq4-3w87"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Splunk MCP Server","requires_auth":"low_privilege","summary":"Attackers can bypass SPL command allowlist controls in Splunk MCP Server by embedding sub-searches, enabling unauthorized actions.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"In Splunk MCP Server app versions below 0.2.4, a user with access to the \"run_splunk_query\" Model Context Protocol (MCP) tool could bypass the SPL command allowlist controls in MCP by embedding SPL commands as sub-searches, leading to unauthorized actions beyond the intended MCP restrictions.","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":"SPL commands allowlist controls bypass in Splunk MCP Server app through \"run_splunk_query\" MCP tool","id":"CVE-2025-20381","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"URL validation bypass through Views Dashboard in Splunk Enterprise","id":"CVE-2025-20382"},"packages":[],"prev":{"headline":"Security feature bypass in Splunk Cloud Platform","id":"CVE-2025-20379"},"products":["Splunk MCP Server"],"published":"2025-12-03","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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-12-03","vendors":["Splunk"]},"summary":"Attackers can bypass SPL command allowlist controls in Splunk MCP Server by embedding sub-searches, enabling unauthorized actions.","url":"https://insights.sbomify.com/CVE-2025-20381/"}
