The gateway agents.files.get and agents.files.set methods allowed symlink traversal for allowlisted workspace files. A symlinked allowlisted file (for example AGENTS.md) could resolve outside the agent workspace and be read/written by the gateway process.

This could enable arbitrary host file read/write within the gateway process permissions, and chained impact up to code execution depending on which files are overwritten.

agents.files now resolves real workspace paths, enforces containment for resolved targets, rejects out-of-workspace symlink targets, and keeps in-workspace symlink targets supported. The patch also adds gateway regression tests for blocked escapes and valid in-workspace symlink behavior.

patched versions is intentionally pre-set to the release (2026.2.25). Advisory published with npm release 2026.2.25.
