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

Status: published. Published: 2026-11-04. Updated: 2026-11-04.

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.
