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-2026-76406/ (Markdown: https://insights.sbomify.com/CVE-2026-76406/index.md)","id":"CVE-2026-76406","markdown":"https://insights.sbomify.com/CVE-2026-76406/index.md","name":"CVE-2026-76406","record":{"aliases":["GHSA-p22x-wc3v-hrj6"],"analysis":null,"analysis_generated_by":null,"assigner":"cisco","cpe":[{"product":"soar","vendor":"splunk"}],"cvss":{"score":5.9,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-203","name":"Observable Discrepancy"}],"description":"In Splunk SOAR versions below 8.7.0, an unauthenticated user with access to encrypted credential data from an affected Splunk SOAR instance could submit Basic authentication data to the Representational State Transfer (REST) API to expose and decrypt that encrypted credential data.\nThe vulnerability is possible because Splunk SOAR decrypts encrypted Basic authentication values before completing authentication checks.\nThe attack requires the unauthenticated user to have encrypted credential data from an affected Splunk SOAR instance.
