OpenClaw has a local file disclosure via sendMediaFeishu in Feishu extension

Summary

The Feishu extension previously allowed sendMediaFeishu to treat attacker-controlled mediaUrl values as local filesystem paths and read them directly.

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 exfiltrate local files by supplying paths such as /etc/passwd as mediaUrl.

Remediation

Upgrade to OpenClaw 2026.2.14 or newer.

Notes

The fix removes direct local file reads from this path and routes media loading through hardened helpers that enforce local-root restrictions.

Fix commit 5b4121d60 confirmed on main and in v2026.2.14. Upgrade to openclaw >= 2026.2.14.
