Vulnerability from github – Published: 2026-05-06 21:31 – Updated: 2026-05-06 21:31

Details

OpenClaw before 2026.4.10 contains an improper network binding vulnerability in the sandbox browser CDP relay that exposes Chrome DevTools Protocol on 0.0.0.0. Attackers can access the DevTools protocol outside intended local sandbox boundaries by exploiting the overly broad binding configuration.

Severity

9.6 (Critical)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
