EPSS is not available and the vulnerability is not listed in CISA\u2019s KEV catalog. The likely attack vector is through a Feishu integration that accepts upload_image requests; an attacker who can influence or supply the upload_image payload can trigger the path traversal and retrieve arbitrary files. Because the flaw allows reading files rather than executing code, the risk is limited to information disclosure, but it could be leveraged in a broader attack chain if sensitive data are exposed."}}}}, "created": "2026-04-28T02:15:18.519592+00:00", "updated": "2026-04-28T13:00:15.206899+00:00", "vendors": ["openclaw", "openclaw$PRODUCT$openclaw"]}
