CVSS v3.1

7.5

High

Base vector

AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N

Name of the Vulnerable Software and Affected Versions OpenClaw versions prior to 2026.2.14

Description The Feishu extension allowed the sendMediaFeishu function to interpret attacker-controlled mediaUrl values as local filesystem paths, enabling direct file reading. An attacker influencing tool calls, potentially through prompt injection, could exfiltrate local files by providing paths like /etc/passwd as the mediaUrl. The fix removes direct local file reads and uses hardened helpers with local-root restrictions for media loading.

Recommendations Upgrade to OpenClaw version 2026.2.14 or newer.
