Duplicate Advisory: Knowns Sandbox Escape: Unauthenticated Header Injection Grants AI Agent Unrestricted Access to Host Filesystem
Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-9h2q-r9fh-f98w. This link is maintained to preserve external references.

Original Description

knowns versions before 0.31.0 fail to properly validate the x-opencode-directory request header in the /api/opencode proxy endpoint. Remote attackers can supply arbitrary directory paths to execute file operations outside the project root on the host system.
