Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-76346 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-2026-76346/ (Markdown: https://insights.sbomify.com/CVE-2026-76346/index.md)","id":"CVE-2026-76346","markdown":"https://insights.sbomify.com/CVE-2026-76346/index.md","name":"CVE-2026-76346","record":{"aliases":["GHSA-mhr2-9p67-2p55"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Splunk Enterprise","requires_auth":"low_privilege","summary":"A power user can inject malicious scripts into dashboard sparklines, allowing execution in other users' browsers and potential privilege escalation.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"splunk","vendor":"splunk"}],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:H/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, a user who holds the \"power\" Splunk role could store a malicious script in dashboard sparkline format options and execute unauthorized JavaScript in the browser of another user who views the dashboard. If the other user holds the \"admin\" Splunk role, the script could access all relevant data available through Splunk Web and perform actions with that user's permissions. The vulnerability is possible because Splunk Web does not limit the permitted dashboard visualization options to safe presentation settings and does not escape tooltip values before rendering them. The vulnerability requires the attacker to phish the affected user by tricking them into initiating a request within their browser. The user who holds the \"power\" Splunk role should not be able to exploit the vulnerability at will.
