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":"2026-09-15T17:17:21.22+00:00","modifiedAt":"2026-09-30T17:51:56.193+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","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/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","https://github.com/mkreyman/mcp-memory-keeper/releases/tag/v0.13.0","https://github.com/mkreyman/mcp-memory-keeper/security/advisories/GHSA-f7wf-v2vw-mpcx"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-54561","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-22","CWE-209"],"productCriteria":[],"sourceDates":{"published":"2026-09-15T17:17:21.220","lastModified":"2026-09-30T17:51:56.193"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
