A vulnerability in the WebSocket endpoint of gpt-researcher v0.14.7 and before allows an unauthenticated remote attacker to achieve code execution via malicious Model Context Protocol configurations.
AnalysisAI
Remote code execution in gpt-researcher v0.14.7 and earlier lets an unauthenticated attacker run arbitrary code on the host by pushing malicious Model Context Protocol (MCP) configurations through the application's WebSocket endpoint. Because the endpoint accepts these configurations without authentication, any network-reachable instance is exploitable with no user interaction, and the MCP config path effectively becomes a command-execution primitive. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires network reachability to the gpt-researcher WebSocket endpoint and the ability to supply a malicious Model Context Protocol (MCP) configuration to it; per the CVSS vector (AV:N/AC:L/PR:N/UI:N) no authentication and no user interaction are needed against an exposed instance. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The raw signals point to top-tier severity: CVSS 9.8 with AV:N/AC:L/PR:N/UI:N and full C/I/A impact means an unauthenticated, low-complexity, network-reachable RCE requiring no user interaction - the worst-case exposure profile. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No vendor-released fixed version is identified in the available data, so a specific upgrade target cannot be cited - monitor the project's site (http://gpt-researcher.com) and the NVD entry (https://nvd.nist.gov/vuln/detail/CVE-2026-37006) for a patched release above 0.14.7 and upgrade as soon as one is published. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all systems running gpt-researcher v0.14.7 or earlier and isolate any internet-facing deployments from public networks or disable external WebSocket access. …
