CVE-2026-58128
Alan: Health Insurance for Android 1.450.0 Path Traversal via ShareReceiverActivity
Description

Alan: Health Insurance for Android (com.alanmobile) 1.450.0 contains a path traversal vulnerability that allows a co-resident malicious application to write attacker-controlled files outside the intended directory via the exported ShareReceiverActivity, which uses an unsanitized _display_name value from a shared content URI to construct the destination file path. Attackers can send a crafted ACTION_SEND intent with a _display_name containing directory traversal sequences to overwrite sensitive files within the app's sandbox such as databases, shared_prefs, and WebView data, enabling state tampering or code execution in the app's context without authentication or user interaction.

Solution
Sanitize user-supplied filenames and validate content URIs before writing files.
  • Validate and sanitize all inputs used for file path construction.
  • Ensure content URIs are properly validated before file operations.
  • Restrict file write operations to intended directories only.
  • Update the application to the latest secure version.
