Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-10277 exists.\n\nAffected product: j3k0 mcp-google-workspace. 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-2026-10277/ (Markdown: https://insights.sbomify.com/CVE-2026-10277/index.md)","id":"CVE-2026-10277","markdown":"https://insights.sbomify.com/CVE-2026-10277/index.md","name":"CVE-2026-10277","record":{"aliases":["GHSA-37j4-5858-49mq"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"MCP Gmail Tool","requires_auth":"low_privilege","summary":"Attackers can bypass access controls in the saveToDisk function to read or modify Gmail data remotely.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulDB","cpe":[],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P","version":"4.0"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"},{"id":"CWE-266","name":"Incorrect Privilege Assignment"}],"description":"A vulnerability was found in j3k0 mcp-google-workspace up to 831790e7d5c2663325733d9f5579cc339a267c4c.
