Aliases CVE-2026-28451
Summary OpenClaw has two SSRF via sendMediaFeishu and markdown image fetching in Feishu extension ### Summary The Feishu extension could fetch attacker-controlled remote URLs in two paths without SSRF protections: - `sendMediaFeishu(mediaUrl)` - Feishu DocX markdown image URLs (write/append -> image processing) ### 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 trigger requests to internal services and re-upload the response as Feishu media. ### Remediation Upgrade to OpenClaw `2026.2.14` or newer. ### Notes The fix routes Feishu remote media fetching through hardened runtime helpers that enforce SSRF policies and size limits.
