CVE-2026-32046
OpenClaw < 2026.2.21 - OS-level Sandbox Bypass via --no-sandbox Flag
OpenClaw versions prior to 2026.2.21 contain an improper sandbox configuration vulnerability that allows attackers to execute arbitrary code by exploiting renderer-side vulnerabilities without requiring a sandbox escape. Attackers can leverage the disabled OS-level sandbox protections in the Chromium browser container to achieve code execution on the host system.

OpenClaw: Chrome --no-sandbox disabled OS-level browser sandbox in sandbox browser container
Summary
Sandbox browser container launched Chromium with --no-sandbox by default, disabling Chromium's OS-level sandbox protections.
Affected Packages / Versions
- Package:
openclaw(npm ecosystem) - Latest published npm version at triage time (2026-02-21):
2026.2.19-2 - Affected range:
<= 2026.2.19-2 - Planned patched version for next release:
2026.2.21
Impact
When --no-sandbox is enabled by default, renderer compromise no longer requires a separate sandbox escape. This weakens container browser isolation and increases impact from renderer-side bugs.
Resolution
- Default
--no-sandboxremoved from sandbox browser entrypoint. - Explicit opt-in added via
OPENCLAW_BROWSER_NO_SANDBOX/CLAWDBOT_BROWSER_NO_SANDBOX. - Browser container hash migration + security audit checks added so stale containers are surfaced and can be recreated safely.

- 1835dec2004fe7a62c6a7ba46b8485f124ec6199
Release Process Note
The advisory patched_versions field is pre-set to the planned next release (2026.2.21). After npm release publication, only advisory publish action should remain.
