CVE-2026-43989

JunoClaw is an agentic AI platform built on Juno Network. Prior to 0.x.y-security-1, the upload_wasm MCP tool accepted a filesystem path from the agent and uploaded whatever bytes the path resolved to, with no validation of location, symlink target, file size, or file format. This vulnerability is fixed in 0.x.y-security-1.

Summary		(es) JunoClaw es una plataforma de IA agéntica construida sobre Juno Network. Antes de 0.x.y-security-1, la herramienta MCP upload_wasm aceptaba una ruta del sistema de archivos del agente y subía cualquier byte al que la ruta se resolviera, sin validación de ubicación, objetivo de enlace simbólico, tamaño de archivo o formato de archivo. Esta vulnerabilidad está corregida en 0.x.y-security-1.
