What is CVE-2026-53866?

OpenClaw, prior to version 2026.5.12, contains a vulnerability in its shell inline-command parsing mechanism that allows authenticated users to execute commands that are not approved. This flaw results from a missing allowlist decision in the parser that fails to appropriately validate command requests. Consequently, operators can send command requests via shell inline-command forms, inadvertently leading to unauthorized command execution without the necessary approval prompts.

Affected Version(s)

OpenClaw 0 < 2026.5.12

OpenClaw 2026.5.12
