OpenClaw: Chrome --no-sandbox disabled OS-level browser sandbox in sandbox browser container

Critical npm

Severity: 0.0 / 10; Critical · CVSS 4.0
Exploit chance (EPSS): 0.30%; Chance of exploitation in the next 30 days. Higher than 22.61% of scored vulnerabilities.
Known exploited: No; Not in CISA's catalog
Weakness: CWE-693 Protection Mechanism Failure
Fix: 2026.2.21; Upgrade openclaw to this version or later

Description

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-sandbox removed 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.
