When `open_visualization` runs, `_find_dev_source()` accepts that directory as a source root if `_is_cortex_root()` finds an `mcp_server/` subdirectory and a `ui/unified-viz.html` file. An attacker who places those two marker files in a malicious repository can make Cortex run `mcp_server/server/visualize_bootstrap.py` from it via `subprocess.run`, executing code with the victim's local user privileges.","solution":"Fixed in 3.17.1.","labels":["security"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-49986","publishedAt":"2026-08-14T17:18:27.147Z","cveId":"CVE-2026-49986","cweIds":["CWE-829"],"cvssScore":null,"cvssSeverity":null,"severity":"high","attackType":["supply_chain","other"],"issueType":"vulnerability","affectedPackages":["neuro-cortex-memory@<= 3.17.0 (fixed: 3.18.0)"],"affectedPackageNames":["neuro-cortex-memory"],"affectedPackageRefs":["pypi:neuro-cortex-memory"],"affectedVendors":[],"affectedVendorsRaw":["Cortex MCP server (neuro-cortex-memory)","Claude Code"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":"Cortex MCP server code execution via malicious project directory","headlinePromptVersion":"h1","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":"unknown","epssScore":0.0016,"epssCheckedAt":"2026-11-14T00:05:45.937Z","kevDateAdded":null,"advisoryAliases":["GHSA-gvpp-v77h-5w8g"],"affectedPackagesSource":"ghsa","affectedPackagesCheckedAt":"2026-10-10T03:45:21.054Z","patchAvailable":true,"disclosureDate":"2026-08-14T17:18:27.147Z","fixReleasedAt":"2026-06-02T13:30:06.146Z","daysToFix":-73,"fixCheckedAt":"2026-10-29T21:31:53.606Z","capecIds":["CAPEC-437"],"crossRefCount":0,"attackSophistication":"moderate","impactType":["confidentiality","integrity"],"aiComponentTargeted":"plugin","llmSpecific":false,"classifierConfidence":0.9,"researchCategory":null,"atlasIds":["AML.T0010"],"fixes":[{"ecosystem":"pypi","name":"neuro-cortex-memory","fixedVersion":"3.18.0","matchedVersion":"3.18.0","fixReleasedAt":"2026-06-02T13:30:06.146Z","daysToFix":-73,"match":"ecosystem","source":"registry","status":"found","checkedAt":"2026-10-29T21:31:53.460Z"}]}}
