CVE-2026-4217Public exploit

Credential disclosure via plaintext cloud token storage

Published Mar 16, 2026 · Updated Mar 16, 2026

Plaintext credential storage in XREAL Nebula App 3.2.0 and 3.2.1 allows local users to read cloud-access credentials on Android. CloudStoragePlugin.java stores its accessKey, secretAccessKey, and securityToken inputs without protecting them at rest. Exploitation requires local low-privileged access and high-complexity preparation; the bounded impact is disclosure of stored credentials.
