Description

Summary

A crafted local avatar path could follow a symlink outside the agent workspace and return arbitrary file contents as a base64 data: URL in gateway responses.

Impact

  • Confidentiality impact: local file read in the gateway process context.
  • Exfiltration path: agents.list can return the resulting avatarUrl payload.

Affected Components

  • src/gateway/session-utils.ts (resolveIdentityAvatarUrl)

Affected Packages / Versions

  • Package: openclaw (npm)
  • Introduced: v2026.1.21
  • Affected published versions: <= 2026.2.21-2
  • Planned patched version: 2026.2.22

Remediation

  • Resolve workspace and avatar paths with realpath and enforce realpath containment.
  • Open files with O_NOFOLLOW when available.
  • Compare pre-open and opened file identity (dev/ino) to block swap races.
  • Add regression tests for outside-workspace symlink rejection and in-workspace symlink allowance.
