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

  • Disclosed: 03.03.2026
  • Updated: 11.10.2026 10:22

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.

Fix Commit(s)

  • 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.

OpenClaw thanks @TerminalsandCoffee for reporting.
