Private channel metadata disclosure via premature resolution
Published Jun 23, 2026 · Updated Jun 23, 2026
Information disclosure in Capgo before 12.128.2 allows remote attackers to expose private OTA channel metadata via crafted /updates requests. The defaultChannel resolver looks up an attacker-supplied name by app ID before checking whether the channel is public, self-settable, or platform-compatible. No authentication is required; attackers who know or guess an app ID and private channel name can distinguish valid channels and read assigned bundle versions and configuration-derived denial reasons.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
