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.","cvssScore":6.2,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","cwes":["CWE-22"],"vendors":[],"products":[],"references":[{"url":"https://github.com/actuator/com.ticktick.task/","tags":[]},{"url":"https://www.vulncheck.com/advisories/ticktick-android-path-traversal-via-sharereceiveactivity","tags":[]}],"exploitRefs":[{"url":"https://github.com/actuator/com.ticktick.task/","tags":[]}],"hasPoc":true,"ai":null}
