From version 2.0.0 through 2.9.2, a lowest-role workspace member denied access to a tool by WorkspaceUserResourcePermission can still bind its identifier through tool_ids, skill_tool_ids, or mcp_tool_ids and execute it through the agent or workflow dispatch path. The dispatch path does not reapply the per-tool grant enforced by dedicated tool routes, and tool execution decrypts server-side init_params, allowing the caller to receive credentials carried by the denied tool. No fixed version is available as of this review.","state":0,"publishedAt":"2026-09-21T20:40:44.213+00:00","modifiedAt":"2026-09-28T20:13:03.315+00:00","affected":[{"ecosystem":"Vendor product","name":"MaxKB","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"1Panel-dev\",\n                    \"product\": \"MaxKB\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 2.0.0, <= 2.9.2\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","score":5.4,"severity":"MEDIUM"}],"references":["https://github.com/1Panel-dev/MaxKB/security/advisories/GHSA-383v-fx78-pphm"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-77516","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-77516","identifiers":["CVE-2026-77516"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
