JunoClaw: upload_wasm accepted arbitrary filesystem paths without validation

Published May 12, 2026 · Updated May 14, 2026 · Assigned by GitHub_M

Description

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.
