CVE-2026-5619 Details
Description
A flaw has been found in Braffolk mcp-summarization-functions up to 0.1.5. This impacts an unknown function of the file src/server/mcp-server.ts of the component summarize_command. Executing a manipulation of the argument command can lead to os command injection. The attack requires local access. The exploit has been published and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
A command injection vulnerability has been identified in Braffolk mcp-summarization-functions versions through 0.1.5. The issue resides in the 'summarize_command' component, specifically within the 'src/server/mcp-server.ts' file. The vulnerability allows local attackers to manipulate the 'command' argument, leading to unauthorized execution of operating system commands via the 'execa' library. This exploitation could result in a complete compromise of the host, including unauthorized data access, integrity violations, and potential disruption of services.
It is recommended to remove direct execution of shell commands from request-driven paths. Replace unvalidated command inputs with fixed allowlists and validated argument schemas. Prefer executing commands as argument arrays without shell interpretation. Additionally, implement authentication, authorization, logging, and rate limiting on sensitive MCP/HTTP handlers.
