CVE-2026-110612
vlife through 2.0.1 contains an authentication bypass vulnerability that allows unauthenticated attackers to forge JWTs using the hardcoded HS256 signing key in TokenUtil.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.00%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
