With EPSS data unavailable and no indication that it has been recorded in the CISA KEV catalog, the established risk is not driven by active exploitation reports yet but by the high potential for widespread compromise, especially in environments that perform out\u2011of\u2011band package resolution. Attackers would need to supply a malicious package or manipulate installation scripts, but once the override is in place, execution of trojanized content is trivial. Because the vulnerability is a supply\u2011chain attack vector, the broad impact could extend to all data and services accessed by the affected applications. In short, the exploitability is medium\u2011low to early\u2011stage, but the severity remains high."}}}}, "created": "2026-04-28T21:30:25.910396+00:00", "updated": "2026-04-28T23:15:43.850181+00:00", "vendors": ["openclaw", "openclaw$PRODUCT$openclaw"]}
