CVE-2026-62674
Omnigent: Shared Agent Bundle Overwrite Leads to Authenticated Runner RCE
Description
Omnigent is an open-source AI agent framework and meta-harness for orchestrating coding agents. Prior to 0.3.0, PUT /sessions/{session_id}/agent checks LEVEL_EDIT permission for a session but does not reject a bound shared or template agent whose agent.session_id is None. An authenticated user with edit access to a session can replace that shared agent bundle through omnigent/server/routes/sessions.py, add a stdio MCP server, and cause later sessions that use the shared agent to launch an attacker-controlled command through omnigent/tools/mcp.py. The command executes with the Omnigent runner process permissions and can expose files, credentials, workspace data, internal services, and runner availability. This issue is fixed in version 0.3.0.

Action Type Old Value New Value Added Translation Title: omnigent de omnigent-ai, Description: Omnigent es un framework de agente de IA de código abierto y un meta-arnés para orquestar agentes de codificación. Antes de la 0.3.0, PUT /sessions/{session_id}/agent verifica el permiso LEVEL_EDIT para una sesión pero no rechaza un agente compartido o de plantilla vinculado cuyo agent.session_id es None. Un usuario autenticado con acceso de edición a una sesión puede reemplazar ese paquete de agente compartido a través de omnigent/server/routes/sessions.py, añadir un servidor MCP stdio, y hacer que sesiones posteriores que utilicen el agente compartido lancen un comando controlado por el atacante a través de omnigent/tools/mcp.py. El comando se ejecuta con los permisos del proceso del ejecutor de Omnigent y puede exponer archivos, credenciales, datos del espacio de trabajo, servicios internos y la disponibilidad del ejecutor. Este problema está solucionado en la versión 0.3.0. -
