OpenClaw has two SSRF via sendMediaFeishu and markdown image fetching in Feishu extension

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.
