Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-76251 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-2026-76251/ (Markdown: https://insights.sbomify.com/CVE-2026-76251/index.md)","id":"CVE-2026-76251","markdown":"https://insights.sbomify.com/CVE-2026-76251/index.md","name":"CVE-2026-76251","record":{"aliases":["GHSA-3pfp-cpmw-f74j"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Splunk Enterprise","requires_auth":"low_privilege","summary":"Unauthorized users can access and modify Splunk Observability Cloud data via REST API endpoints due to missing capability checks.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"splunk","vendor":"splunk"}],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"In Splunk Enterprise versions below 10.4.2, 10.2.6, and 10.0.9, a user who does not hold the \"admin\" or \"power\" Splunk roles could cause the Splunk App for Splunk Observability Cloud to forward requests to Splunk Observability Cloud, including the Splunk Observability Cloud access token stored for the app. With this access, the user could view all relevant data available to that token and make limited changes to Splunk Observability Cloud content. The vulnerability does not affect Splunk Enterprise 9.4 and 9.3 versions. The vulnerability is possible because the app's Representational State Transfer (REST) API endpoint handlers do not enforce the read_o11y_content capability before forwarding requests with the stored access token.
