CVE-2026-27566
OpenClaw's exec allowlist wrapper analysis did not unwrap env/shell dispatch chains
Description
### Summary `system.run` exec allowlist analysis treated wrapper binaries as the effective executable and did not fully unwrap `env`/shell-dispatch wrappers. This allowed wrapper-smuggled payloads (for example `env bash -lc ...`) to satisfy an allowlist entry for the wrapper while executing non-allowlisted commands. ### Impact On affected versions, an actor who can trigger `system.run` requests under an allowlist policy could bypass intended allowlist restrictions by routing execution through wrapper binaries. ### Affected Packages / Versions - Package: `openclaw` (npm) - Affected: `<= 2026.2.21-2` - Patched in next release: `2026.2.22` (pre-set below so publish can happen immediately after npm release) ### Fix Commit(s) - `2b63592be57782c8946e521bc81286933f0f99c7` ### Release Process Note `patched_versions` is pre-set to the planned next release (`>= 2026.2.22`). After npm `2026.2.22` is published, this advisory can be published directly without further metadata edits. OpenClaw thanks @tdjackey for reporting.
