CVE-2026-56322 Details
Description
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.
An information disclosure vulnerability has been identified in Capgo versions prior to 12.128.2. The issue resides in the unauthenticated '/updates' endpoint, which processes the 'defaultChannel' parameter without first applying necessary privacy controls. This flaw allows attackers to enumerate private channels and extract version and configuration information. Unauthenticated attackers can send requests to the '/updates' endpoint with channel names, distinguishing between valid private channels and nonexistent ones based on the differences in responses. The vulnerability reveals assigned bundle versions and platform-specific configuration details, creating a privacy risk around internal rollout channels.
Users are advised to update to Capgo version 12.128.2 or later.
