OpenClaw 2026.2.6 < 2026.3.28 - Arbitrary File Read via Feishu upload_image Parameter
OpenClaw versions 2026.2.6 through 2026.3.24 contain a path traversal vulnerability in the Feishu extension resolveUploadInput function that bypasses file-system sandbox restrictions. Attackers can exploit improper path resolution during upload_image operations to read arbitrary files outside configured localRoots boundaries.
