EPSS is not available, and the vulnerability is not listed in the CISA KEV catalog. Because the flaw arises only when sandboxRoot is unset, the likely attack vector is local; an attacker with access to the running application can perform a file read of any system file within the runtime user's permissions. In environments where the application runs with elevated privileges, the risk of broader compromise increases. The absence of a publicly known workaround underscores the importance of applying the patch promptly."}}}}, "created": "2026-03-18T10:42:07.298265+00:00", "updated": "2026-03-24T10:53:36.130867+00:00", "vendors": ["openclaw", "openclaw$PRODUCT$openclaw"]}
