Explain, at a high level, the CVE-2026-25253 vulnerability and how OpenClaw addressed it?

CVE-2026-25253 was a high-severity vulnerability, rated 8.8 on the CVSS scale, that allowed remote code execution triggered through a malicious webpage, requiring only a single click of interaction from the user.

• The vulnerability involved how the agent's browser-automation tooling processed content encountered while browsing, allowing crafted page content to trigger unintended code execution
• It was patched in OpenClaw's 2026.1.29 release
• Follow-on findings related to Docker sandbox handling were separately addressed in the 2026.2.15 release

This case is frequently cited in OpenClaw security discussions as a concrete illustration of why browser-automation tools are treated as higher-risk and why sandboxing that specific tool category is a commonly recommended precaution, even when sandboxing everything else is skipped.
