A security flaw has been discovered in iAI Lab PDF AI App 4.21.0 on Android. Impacted is the function getExternalCacheDir of the component chatpdf.pro. Performing a manipulation of the argument _display_name results in path traversal. The attack requires a local approach. The exploit has been released to the public and may be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.
