It is not currently listed in the CISA KEV catalog. The exploit requires remote access to the ACS endpoint and the ability to craft a TR\u2011069 Download URL that is passed unescaped into the firmware upgrade pipeline. The attack vector is thus remote, and only customers exposing their ACS to untrusted networks are at immediate risk. Due to the low exploit probability, widespread exploitation has not been reported, but the severity warrants swift action."}}}}, "created": "2026-03-20T08:58:05.363871+00:00", "updated": "2026-03-25T11:51:42.527987+00:00", "vendors": ["freedomfi", "freedomfi$PRODUCT$sercomm_sce4255w"]}
