## What is CVE-2026-89038?

CVE-2026-89038 is a medium-severity path traversal vulnerability in Verizon Cloud for Android, published on 17 Sep 2026. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

Verizon Cloud for Android (com.vcast.mediamanager) before 26.7.10 contains a path traversal vulnerability that allows co-resident malicious applications to write attacker-controlled bytes outside the intended staging directory by supplying a crafted _display_name value containing path-traversal sequences through exported activities OneTouchUploadActivity and PrintShopCloudActivity. Attackers can exploit the unsanitized filename concatenation in the file-staging sink via ACTION_SEND or ACTION_SEND_MULTIPLE intents to achieve arbitrary file write and inject attacker-controlled content into the authenticated user's Verizon Cloud account without user interaction.

Weakness: CWE-22 (Improper Limitation of a Pathname to a Restricted Directory)
