## Overview

TickTick Android application (com.ticktick.task) 8.2.2.0 contains a path traversal vulnerability in its exported ShareReceiveActivity that allows a malicious local application to write files outside the intended attachment directory by supplying a crafted content:// URI with a traversal filename via ACTION_SEND intents. A malicious application can register a ContentProvider returning a _display_name value containing traversal sequences, which is passed unsanitized through FileManager.getDisplayNameFromUri and AttachmentFileHelper.copyFileDirectly, causing automatic file writes to attacker-chosen locations with TickTick's application privileges.

## Affected

- `ticktick_for_android 8.2.2.0`
