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.","cvss_v4":null,"cvss_v3":{"version":"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},"cwes":["CWE-22","CWE-209"],"references":["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/issues/35","https://github.com/mkreyman/mcp-memory-keeper/pull/36"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:53:43.293028046+00:00"},"epss":{"cve":"CVE-2026-54561","score":0.00249,"percentile":0.16119,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-f7wf-v2vw-mpcx","url":"https://osv.dev/vulnerability/GHSA-f7wf-v2vw-mpcx","summary":"mcp-memory-keeper: Arbitrary local file read in context_import via unvalidated filePath","modified":"2026-07-31T05:15:33.861007462Z","packages":[{"ecosystem":"npm","name":"mcp-memory-keeper","purl":"pkg:npm/mcp-memory-keeper","ranges":["<0.13.0"],"fixed":["0.13.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
