What is CVE-2026-11319?
CVE-2026-11319 is a medium-severity path traversal vulnerability in TickTick for Android, published on 19 Oct 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
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.
Weakness: CWE-22
