The EPSS score is listed as < 1\u202f%, meaning the likelihood of exploitation in the wild is very low, and it is not currently present in the CISA KEV catalog. The attack vector is inferred to be local; an authorized user must execute the exploit from within the operating system, so remote exploitation is not described by the data. The combination of a moderate CVSS score and low EPSS suggests that the risk is manageable but should be mitigated promptly."}}}}, "created": "2026-04-20T16:15:11.020949+00:00", "updated": "2026-04-20T16:15:11.020959+00:00", "vendors": []}
