Because the marketplace.ts module does not limit where a redirect can point, an attacker can supply a URL that is redirected to an arbitrary internal or external server. The result is that the OpenClaw server, acting as an intermediary, will send requests to the attacker\u2011controlled target, leaking information about the internal network and possibly exposing services that should be internal only. The primary consequence is the compromise of confidentiality and potential lateral movement within the internal infrastructure.", "risk_and_exploitability": "The CVSS score of 4.8 classifies the vulnerability as medium severity. No EPSS figure is available, and it is not listed in the CISA KEV catalog.
