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.\n\n## Affected\n\n- `ticktick_for_android 8.2.2.0`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":46,"depthScoreParts":{"impact":34.1,"likelihood":0,"exploitation":12,"ransomware":0},"changes":[{"seq":227850,"id":"CVE-2026-11319","ts":1792706837803,"field":"exploit_available","old":"false","new":"true"}]}
