CVE-2026-26321

OpenClaw has a local file disclosure via sendMediaFeishu in Feishu extension

7.5 HighFix available

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.
