Summary

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

Details

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.

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.

Vulnerability from cvelistv5 – Published: 2026-03-21 00:42 – Updated: 2026-03-23 17:44 X_Open Source

Title

OpenClaw < 2026.2.21 - OS-level Sandbox Bypass via --no-sandbox Flag

Summary

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.
