This flaw allows remote attackers to potentially bypass intended security restrictions, leading to unauthorized access or modification of data. Publicly available exploit code exists, increasing the risk of exploitation. The vulnerability is identified as CVE-2026-7505. Organizations using affected versions of GoClaw or GoClaw Lite should upgrade to version 3.9.0, which includes a patch (406022e79f4a18b3070a446712080571eff11e30) to mitigate this issue.
