CVE-2019-12370Public exploitNetwork attack vector

Script execution and local file loading via email

Published Mar 18, 2020 · Updated Aug 4, 2024

Cross-site scripting in Readdle Spark 2.0.2 and earlier for Android allows remote attackers to run script through a crafted email. The HTML email renderer processes attacker-supplied event attributes as executable script and resolves src attributes to arbitrary local files. Exploitation requires the recipient to view the crafted message; local-file loading additionally requires READ_EXTERNAL_STORAGE permission.
