Prior to 0.13.0, context_import in src/index.ts passes the caller-controlled filePath directly to fs.readFileSync without restricting the path to an export directory. An MCP client, including an LLM agent induced to call the tool, can use ../ traversal or an absolute path to target any file readable by the server process. A valid JSON file is parsed and imported into the caller's session, allowing its full contents to be retrieved through context_get or context_export, while JSON.parse errors for non-JSON files can return leading file bytes in a SyntaxError message. The two disclosure modes can expose other exported sessions, JSON credentials or service-account files, environment files, and portions of SSH keys or other local files. This issue is fixed in version 0.13.0.","state":0,"publishedAt":"2026-09-15T16:32:01.307+00:00","modifiedAt":"2026-09-15T17:28:58.028+00:00","affected":[{"ecosystem":"Vendor product","name":"mcp-memory-keeper","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"mkreyman\",\n                    \"product\": \"mcp-memory-keeper\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 0.13.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":6.2,"severity":"MEDIUM"}],"references":["https://github.com/mkreyman/mcp-memory-keeper/security/advisories/GHSA-f7wf-v2vw-mpcx","https://github.com/mkreyman/mcp-memory-keeper/issues/35","https://github.com/mkreyman/mcp-memory-keeper/pull/36","https://github.com/mkreyman/mcp-memory-keeper/commit/58640c22e037572e0b03bc0aa25d015ea98dcc6d","https://github.com/mkreyman/mcp-memory-keeper/commit/b9369568468007c85f8aec3ae09ca6f611285bc5","https://github.com/mkreyman/mcp-memory-keeper/commit/e0ab521a9e8343bcab1ca60ccc3601e4d86eaa97","https://github.com/mkreyman/mcp-memory-keeper/releases/tag/v0.13.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-54561","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-54561","identifiers":["CVE-2026-54561"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
