Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-76395 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-2026-76395/ (Markdown: https://insights.sbomify.com/CVE-2026-76395/index.md)","id":"CVE-2026-76395","markdown":"https://insights.sbomify.com/CVE-2026-76395/index.md","name":"CVE-2026-76395","record":{"aliases":["GHSA-wmwx-pqh3-xv86"],"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":"low_privilege","summary":"A user with the power role can execute arbitrary code on the Splunk server by uploading a crafted model file with malicious pickle data.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"ai_toolkit","vendor":"splunk"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"In Splunk AI Toolkit versions below 6.0.0, a user who holds the \"power\" Splunk role could execute arbitrary code on the Splunk server by loading a model file containing crafted sparse matrix data.
