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-2026-101084 exists.\n\nAffected packages and fixed versions:\n- github.com/obot-platform/obot (Go): affected all versions; fixed in 0.21.1\n- github.com/obot-platform/obot (Go): affected all versions; fixed in 0.21.1\n- github.com/obot-platform/obot (Go): affected all versions; fixed in 0.21.1\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-2026-101084/ (Markdown: https://insights.sbomify.com/CVE-2026-101084/index.md)","id":"CVE-2026-101084","markdown":"https://insights.sbomify.com/CVE-2026-101084/index.md","name":"CVE-2026-101084","record":{"aliases":["GHSA-g524-9c6h-8w7v","GHSA-vw82-7fv8-r6gp","GO-2026-5678"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["privilege_escalation","data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"MCP server platform","requires_auth":"low_privilege","summary":"Authenticated users can bypass authorization on the /mcp-connect endpoint to access restricted MCP servers and manipulate backend systems.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","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:N/SC:H/SI:H/SA:N","version":"4.0"},"cwes":[{"id":"CWE-639","name":"Authorization Bypass Through User-Controlled Key"}],"description":"obot versions before v0.21.1 fail to enforce Access Control Rules on the /mcp-connect endpoint, allowing any authenticated user to connect to restricted MCP servers if they possess the server ID.
