Exploitability
| CWE ID | Description |
|---|---|
| CWE-22 | The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. |

AI Powered Q&A
Can you explain this vulnerability to me?
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.
How can this vulnerability impact me? :
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.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:

What immediate steps should I take to mitigate this vulnerability?
To mitigate this vulnerability, upgrade OpenClaw to version 2026.2.14 or newer.
The fix in this version removes direct local file reads from the vulnerable path and routes media loading through hardened helpers that enforce local-root restrictions.
