CVE-2026-56328: Capgo

Medium severity, CVSS 6.5. EPSS: 0.3% chance of exploitation in the next 30 days.

Capgo before 12.128.2 allows multiple public channels for the same app and platform to coexist simultaneously, while unnamed /updates requests without defaultChannel implicitly resolve to a single hidden winner channel. An authorized app or channel manager can create ambiguous default update state and silently influence which bundle unnamed clients receive, breaking release routing integrity and predictability.
