Description
Summary
The Feishu extension previously allowed sendMediaFeishu to treat attacker-controlled mediaUrl values as local filesystem paths and read them directly.
Affected versions
Patched versions
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.
NVD description
OpenClaw is a personal AI assistant. Prior to OpenClaw version 2026.2.14, the Feishu extension previously allowed `sendMediaFeishu` to treat attacker-controlled `mediaUrl` values as local filesystem paths and read them directly. 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`. Upgrade to OpenClaw `2026.2.14` or newer to receive a fix. The fix removes direct local file reads from this path and routes media loading through hardened helpers that enforce local-root restrictions.
