This dual use of an authentication secret across security domains enables an attacker who can observe the prompts sent to third\u2011party model providers to mathematically derive the gateway authentication token from the hash output, thereby compromising authentication and potentially allowing unauthorized access to the system. The weakness lies in improper key reuse (CWE\u2011320).", "risk_and_exploitability": "The CVSS score is 6.3, indicating moderate severity. EPSS data is not available and the vulnerability is not listed in CISA's KEV catalog. The attack vector requires an attacker to have access to the system prompts that are transmitted to external model providers; it does not require network connectivity to the OpenClaw service itself. Once the token is derived, an attacker can authenticate to the gateway. Because the flaw is not exploitable for arbitrary code execution or denial of service, the risk is focused on credential compromise rather than disruption of service."}}}}, "created": "2026-03-23T09:51:12.760648+00:00", "updated": "2026-03-25T14:42:48.816472+00:00", "vendors": ["openclaw", "openclaw$PRODUCT$openclaw"]}
