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.
AnalysisAI
OpenClaw versions prior to 2026.2.21 contain an improper sandbox configuration vulnerability (CWE-1188) that allows local attackers with low privileges to execute arbitrary code on the host system by exploiting disabled OS-level sandbox protections in the Chromium browser container. The vulnerability does not require a sandbox escape, making exploitation straightforward for local users. …

Vulnerability AssessmentAI
| Risk Assessment | The CVSS 3.1 score of 5.3 (Medium severity) reflects the local attack vector (AV:L), low attack complexity (AC:L), and low privilege requirement (PR:L), indicating realistic exploitability by local users without special knowledge. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A local user on a shared OpenClaw system identifies that the Chromium renderer sandbox is disabled due to improper configuration. They craft a malicious webpage or leverage a pre-existing renderer vulnerability (e.g., a use-after-free in the V8 engine) to achieve code execution within the renderer process. … |
| Remediation | Upgrade OpenClaw to version 2026.2.21 or later immediately, following the vendor security advisory at https://github.com/openclaw/openclaw/security/advisories/GHSA-43x4-g22p-3hrq. … Detailed patch versions, workarounds, and compensating controls in full report. |
