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-2026-9589/ (Markdown: https://insights.sbomify.com/CVE-2026-9589/index.md)","id":"CVE-2026-9589","markdown":"https://insights.sbomify.com/CVE-2026-9589/index.md","name":"CVE-2026-9589","record":{"aliases":["GHSA-m9mc-chm4-qcpm"],"analysis":null,"analysis_generated_by":null,"assigner":"NCSC.ch","cpe":[],"cvss":{"score":9.3,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"},{"id":"CWE-639","name":"Authorization Bypass Through User-Controlled Key"}],"description":"Missing authorization in the configuration cascade operations of the Collaboration Server in Unblu inc. Unblu Spark 7.0 through 8.36.1-hotfix.0, on on-premises and cloud deployments, allows an authenticated remote attacker to read and change configuration properties of entities they aren't authorized to access, including other users, other accounts and, in Unblu Cloud, other customers' accounts, via configuration read and write operations that target those entities.\n\nThe Collaboration Server doesn't check whether the user reading or changing configuration has access to the entity the configuration belongs to.
