Exploitability is unclear because the EPSS score is not available and the vulnerability is not listed in CISA\u2019s KEV catalog.

The impact is information disclosure rather than code execution or denial of service, limiting the scope but still posing a confidentiality risk."}}}}, "created": "2026-04-16T09:00:05.297892+00:00", "title": "Incorrect Destination Specification Leading to Unintended Communication and Information Disclosure in Arcserve UDP Console", "updated": "2026-04-16T09:11:54.846199+00:00", "vendors": ["arcserve", "arcserve$PRODUCT$udp_console"]}
