This creates a prototype pollution flaw that can be used to alter built\u2011in object prototypes. Because the /debug set is protected by a command gate, an attacker who is authorized to use this API can inject these keys and bypass the gate, potentially executing arbitrary code. The flaw is classified as CWE\u20111321: Prototype Pollution.", "risk_and_exploitability": "The CVSS base score is 2.3, reflecting a low severity. The EPSS score is not available and the vulnerability is not listed in CISA's KEV catalog. Exploitation requires an authenticated caller that has permission to invoke the /debug set API, which is typically a privileged user or developer environment. If this access is available, an attacker can modify prototypes and bypass authentication controls, suggesting a higher impact in that context. Overall, the risk is low for general users but could become significant if the /debug API is exposed to untrusted parties."}}}}, "created": "2026-03-18T10:42:05.556804+00:00", "updated": "2026-03-24T10:53:34.244862+00:00", "vendors": ["openclaw", "openclaw$PRODUCT$openclaw"]}
