Answer in brief
CVE-2026-56254 records a High severity (CVSS 7.0) vulnerability in capacitor-updater - End-to-End Encryption Bypass via Private Key Distribution. The current sources do not mark it as known exploited. The current feed maps capacitor-updater/capacitor-updater (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 7.0. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

In @capgo/capacitor-updater (Cap-go/capgo) before 12.128.2, the end-to-end encryption scheme distributes the private key to each device that downloads the app. Because the public key can be derived from the private key, an attacker performing a man-in-the-middle attack or compromising the Capgo server can create a validly signed update bundle and cause devices to install an update not produced by the original app maker.
