Last modified

CVE-2026-56322 is a high-severity vulnerability rated 8.7/10 on the CVSS scale. Capgo before 12.128.2 contains an information disclosure vulnerability in the unauthenticated /updates endpoint that resolves the defaultChannel parameter before enforcing privacy restrictions, allowing attackers to enumerate private channels and leak version/config state. Unauthenticated attackers can probe private channel names and distinguish valid channels from nonexistent ones based on response differences, revealing assigned bundle versions and platform-specific configuration details.. EPSS estimates a 0.33% chance of exploitation in the next 30 days.
