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-2026-93328/ (Markdown: https://insights.sbomify.com/CVE-2026-93328/index.md)","id":"CVE-2026-93328","markdown":"https://insights.sbomify.com/CVE-2026-93328/index.md","name":"CVE-2026-93328","record":{"aliases":["GHSA-2gc9-c85v-5vwr"],"analysis":null,"analysis_generated_by":null,"assigner":"GoogleCloud","cpe":[],"cvss":{"score":9.3,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:L/SI:L/SA:L/U:Amber","version":"4.0"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"},{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"Path Traversal and Missing Authorization in cloud-storage source in Google Cloud MCP Toolbox for Databases (googleapis/mcp-toolbox) versions 1.2.0 through 1.4.0 allows an unauthenticated remote attacker to exfiltrate host files to external Google Cloud Storage buckets and overwrite arbitrary local files via crafted tool invocation parameters.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-10-27","github_poc":1,"max_poc_stars":1,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-10-27T05:07:58Z","kind":"github_poc","ref":"https://github.com/sustilliano/cve-2026-93328-gate","stars":1,"title":"The authorization layer CVE-2026-93328 was missing: scoped grants, path confinement, and signed receipts in front of MCP storage tools.
