An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-76356 in the wild and no public exploit code.\n\nAffected product: Splunk SOAR. 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-2026-76356/ (Markdown: https://insights.sbomify.com/CVE-2026-76356/index.md)","id":"CVE-2026-76356","markdown":"https://insights.sbomify.com/CVE-2026-76356/index.md","name":"CVE-2026-76356","record":{"aliases":["GHSA-q6gh-xv9g-wf4c"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution","data_read","data_modify","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Splunk SOAR","requires_auth":"none","summary":"Unauthenticated attackers can spoof IP headers to bypass authentication and execute arbitrary code on Splunk SOAR hosts.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"soar","vendor":"splunk"}],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-290","name":"Authentication Bypass by Spoofing"}],"description":"In Splunk SOAR versions below 8.6.0, an unauthenticated user could spoof the source IP address in a crafted request to an Automation Broker notification endpoint and execute arbitrary code on the Splunk SOAR host. The vulnerability is possible because the Splunk SOAR Automation Broker trusts a client-supplied source IP address header as proof that the request originates from the local system. Successful exploitation can expose all relevant data, affect system integrity, and disrupt service availability.
