CVE-2026-26321
OpenClaw has a local file disclosure via sendMediaFeishu in Feishu extension
Description
### Summary The Feishu extension previously allowed `sendMediaFeishu` to treat attacker-controlled `mediaUrl` values as local filesystem paths and read them directly. ### Affected versions - `< 2026.2.14` ### Patched versions - `>= 2026.2.14` ### 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`.
