2026.2.14- Upgrade openclaw to this version or later
Description
Summary
The Feishu extension could fetch attacker-controlled remote URLs in two paths without SSRF protections:
sendMediaFeishu(mediaUrl)- Feishu DocX markdown image URLs (write/append -> image processing)
Affected versions
< 2026.2.14
Patched versions
>= 2026.2.14
Impact
If an attacker can influence tool calls (directly or via prompt injection), they may be able to trigger requests to internal services and re-upload the response as Feishu media.
Remediation
Upgrade to OpenClaw 2026.2.14 or newer.
Notes
The fix routes Feishu remote media fetching through hardened runtime helpers that enforce SSRF policies and size limits.

How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.
