Local File Read Vulnerability in OpenClaw Feishu Extension

Publication date: 2026-02-19

Last updated on: 2026-02-20

Assigner: GitHub, Inc.

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.

Executive Summary

This vulnerability exists in OpenClaw's Feishu extension prior to version 2026.2.14. The function `sendMediaFeishu` improperly treats attacker-controlled `mediaUrl` values as local filesystem paths, allowing an attacker to read local files directly. If an attacker can influence tool calls, either directly or through prompt injection, they can supply paths like `/etc/passwd` as `mediaUrl` to exfiltrate sensitive local files.

The issue is fixed in OpenClaw version 2026.2.14 and later by removing direct local file reads from this path and routing media loading through hardened helpers that enforce local-root restrictions.

Impact Analysis

This vulnerability can lead to unauthorized disclosure of sensitive local files on the system where OpenClaw is running. An attacker exploiting this flaw can read critical files such as system password files, potentially gaining access to sensitive information without any privileges or user interaction.

The CVSS score of 7.5 indicates a high severity impact, specifically a high confidentiality impact with no required privileges or user interaction.
