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."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"mkreyman","product":"mcp-memory-keeper","versions":[{"version":"< 0.13.0","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","baseScore":6.2,"baseSeverity":"MEDIUM","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"NONE","availabilityImpact":"NONE"},"exploitabilityScore":2.5,"impactScore":3.6}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-09-15T17:28:40.655510Z","id":"CVE-2026-54561","options":[{"exploitation":"poc"},{"automatable":"no"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-22"},{"lang":"en","value":"CWE-209"}]}],"references":[{"url":"https://github.com/mkreyman/mcp-memory-keeper/commit/58640c22e037572e0b03bc0aa25d015ea98dcc6d","source":"security-advisories@github.com"},{"url":"https://github.com/mkreyman/mcp-memory-keeper/commit/b9369568468007c85f8aec3ae09ca6f611285bc5","source":"security-advisories@github.com"},{"url":"https://github.com/mkreyman/mcp-memory-keeper/commit/e0ab521a9e8343bcab1ca60ccc3601e4d86eaa97","source":"security-advisories@github.com"},{"url":"https://github.com/mkreyman/mcp-memory-keeper/issues/35","source":"security-advisories@github.com"},{"url":"https://github.com/mkreyman/mcp-memory-keeper/pull/36","source":"security-advisories@github.com"},{"url":"https://github.com/mkreyman/mcp-memory-keeper/releases/tag/v0.13.0","source":"security-advisories@github.com"},{"url":"https://github.com/mkreyman/mcp-memory-keeper/security/advisories/GHSA-f7wf-v2vw-mpcx","source":"security-advisories@github.com"},{"url":"https://github.com/mkreyman/mcp-memory-keeper/issues/35","source":"134c704f-9b21-4f2e-91b3-4a467353bcc0"}]}
