CVE-2026-3671 Details
Description
A flaw has been found in Freedom Factory dGEN1 up to 20260221. Affected by this vulnerability is the function TokenBalanceContentProvider of the component org.ethereumphone.walletmanager.testing123. Executing a manipulation can lead to improper authorization. The attack requires local access. The exploit has been published and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
A broken authorization vulnerability has been identified in the Freedom Factory dGEN1 phone, specifically in the wallet application package 'org.ethereumphone.walletmanager.testing123'. This vulnerability arises from an exported ContentProvider, 'TokenBalanceContentProvider', which exposes user wallet balance data without proper read permissions or caller validation. As a result, any unprivileged local application can access and enumerate a user's token balances. This data can be cross-referenced with blockchain information to infer the user's wallet address and on-chain holdings, leading to a privacy breach.
To address this vulnerability, it is recommended to define and enforce a read permission with signature protection, validate callers using the calling UID and package verification, and restrict the provider export if external access is not needed. Additionally, sensitive balance metadata should not be exposed through globally accessible inter-process communication interfaces.
