CVE-2026-108506 · Severity: medium · CVSS 5.5 · Published 2026-10-10

The ZTE Z80 Ultra smartphone has system interfaces that lack proper authentication and access controls. Third-party applications can bypass these protections using code reflection techniques to access sensitive device information without user permission, potentially exposing personal data or system credentials.

## Technical details

The Z80 Ultra's system interfaces lack robust invocation authentication and access control mechanisms. Third-party applications can use Java reflection to directly invoke these interfaces and retrieve sensitive information that should be restricted. This is a local-vector vulnerability requiring application installation but no user interaction beyond normal app permissions.
