OpenClaw has agent avatar symlink traversal in gateway session metadata
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.listcan return the resultingavatarUrlpayload.
Affected Components
src/gateway/session-utils.ts(resolveIdentityAvatarUrl)
Affected Packages / Versions
- Package:
openclaw(npm) - Introduced:

Remediation
- Resolve workspace and avatar paths with
realpathand enforce realpath containment. - Open files with
O_NOFOLLOWwhen 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.
