CVE-2026-35503
A vulnerability in SenseLive X3050’s web management interface allows authentication logic to be performed entirely on the client side, relying on hardcoded values within browser-executed scripts rather than server-side verification.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.55%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
