WiseConnect: Authentication Bypass by Primary Weakness
CVE-2026-19292 is a high-severity authentication bypass by primary weakness vulnerability in WiseConnect from Silabs.com, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited from the same local network by an unauthenticated attacker, without any action from a user. The record lists versions 4.1.0, 2.14.0 as the first without the flaw, so updating WiseConnect to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.35% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update WiseConnect to 4.1.0 or 2.14.0, whichever matches your release line, or a later version.

The underlying weakness: Authentication Bypass by Primary Weakness
The authentication algorithm is sound, but the implemented mechanism can be bypassed as the result of a separate weakness that is primary to the authentication error.
