Title
Chess Play and Learn App com.chess AndroidManifest.xml backup
Summary
A weakness has been identified in Chess Play and Learn App up to 4.9.42 on Android. This issue affects some unknown processing of the file AndroidManifest.xml of the component com.chess. This manipulation causes exposure of backup file to an unauthorized control sphere. It is feasible to perform the attack on the physical device. The exploit has been made available to the public and could be used for attacks. Upgrading the affected component is advised. The vendor was informed early about this issue. They confirmed the existence and that they will address it. Furthermore, they explain that their bug bounty "explicitly excludes physical-access attacks". However, they appreciate the quality of the report and aim at making a goodwill payment to the researcher.

Title
AliasVault App Backup aliasvault.xml backup
Summary
A vulnerability was identified in AliasVault App up to 0.25.3 on Android/iOS. This vulnerability affects unknown code of the file shared_prefs/aliasvault.xml of the component Backup Handler. The manipulation of the argument accessToken/refreshToken/metadata/key_derivation_params/auth_methods leads to exposure of backup file to an unauthorized control sphere. An attack has to be approached locally. The attack is considered to have high complexity. It is stated that the exploitability is difficult. The exploit is publicly available and might be used. Upgrading to version 0.26.0 is able to resolve this issue. The identifier of the patch is 873ecc03f92238e162f98a068ad56069a922b4f6/0bd662320174d8265dfe3b05a04bc13efc960532. It is recommended to upgrade the affected component. The creator of the software explains: "Because of AliasVault's zero-knowledge encryption design, the tokens stored in aliasvault.xml are API session tokens that cannot decrypt the vault on their own: the master password is required for that. So while this isn't a direct vault compromise risk, there's no reason to include them in backups either."
