The Tasks.org app uses the activity `ShareLinkActivity.kt` to handle \"share\" intents coming from other components in the same device and convert them to tasks. Those intents may contain arbitrary file paths as attachments, in which case the files pointed by those paths are copied in the app's external storage directory. Prior to versions 12.7.1 and 13.0.1, those paths were not validated, allowing a malicious or compromised application in the same device to force Tasks.org to copy files from its internal storage to its external storage directory, where they became accessible to any component with permission to read the external storage. This vulnerability can lead to sensitive information disclosure. All information in the user's notes and the app's preferences, including the encrypted credentials of CalDav integrations if enabled, could be accessed by third party applications installed on the same device. This issue was fixed in versions 12.7.1 and 13.0.1. There are no known workarounds."}, {"lang": "es", "value": "La aplicaci\u00f3n Tasks.org para Android es una aplicaci\u00f3n de c\u00f3digo abierto para listas de tareas y recordatorios.
