This vulnerability allows remote attackers to disclose stored credentials on affected installations of OpenClaw. User interaction is required to exploit this vulnerability in that the target must initiate an OAuth authorization flow.\n\nThe specific flaw exists within the implementation of OAuth authorization. The issue results from the exposure of sensitive data in the authorization URL query string. An attacker can leverage this vulnerability to disclose stored credentials, leading to further compromise.
