From 0.2.0 until 0.3.1, the Global Prompts feature stores a prompt template without sufficient output encoding before the MCP Admin UI renders it. An authenticated attacker can save markup containing script-capable event handlers, and the code executes when another user views the saved prompt. The stored cross-site scripting can alter the interface, present phishing content, observe keystrokes available to the page, and act with the viewer's browser session. This issue is fixed in version 0.3.1.","state":0,"publishedAt":"2026-10-13T14:34:01.069+00:00","modifiedAt":"2026-10-13T15:48:27.245+00:00","affected":[{"ecosystem":"Vendor product","name":"mcp-context-forge","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"IBM\",\n                    \"product\": \"mcp-context-forge\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 0.2.0, < 0.3.1\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N","score":5.1,"severity":"MEDIUM"}],"references":["https://github.com/IBM/mcp-context-forge/security/advisories/GHSA-x6gc-rm5j-55mw","https://github.com/IBM/mcp-context-forge/pull/337","https://github.com/IBM/mcp-context-forge/commit/acd16196158f9a393187551b21a2fc61650f2e3d","https://github.com/IBM/mcp-context-forge/releases/tag/v0.3.1"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-53711","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-53711","identifiers":["CVE-2026-53711"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
