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.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for openclaw, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update openclaw to 2026.2.22 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-9mph-4f7v-fmvh is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
