CVE-2026-89038 Verizon CVE debrief

Who should care

Defenders responsible for managing and securing Android devices with the Verizon Cloud application installed should be aware of this vulnerability and take steps to verify and update the application version.

Why it matters

The CVE-2026-89038 path traversal vulnerability in Verizon Cloud for Android allows co-resident malicious applications to write attacker-controlled bytes outside the intended staging directory, potentially leading to unauthorized data modification or injection of malicious content into the authenticated user's Verizon Cloud account.

• Verify the version of Verizon Cloud for Android installed on devices and ensure it is updated to 26.7.10 or later to prevent exploitation.
• Monitor for suspicious activity related to the OneTouchUploadActivity and PrintShopCloudActivity exported activities to detect potential exploitation attempts.
• Implement additional security controls to prevent co-resident malicious applications from exploiting the vulnerability and writing attacker-controlled bytes outside the intended staging directory.

Technical summary

The Verizon Cloud for Android application 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. The vulnerability can be exploited 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. The issue affects versions before 26.7.10 and can be mitigated by verifying the version of Verizon Cloud for Android installed

Defensive priority

Defenders should prioritize verifying the version of Verizon Cloud for Android installed on devices and ensuring that it is updated to 26.7.10 or later.

Recommended defensive actions

• Monitor for suspicious activity related to the OneTouchUploadActivity and PrintShopCloudActivity exported activities.
• Implement additional security controls to prevent co-resident malicious applications from exploiting the vulnerability.
• Review compensating controls for exposed systems while remediation is scheduled and verified.
• Check relevant monitoring, detection, and logs for exposed assets that need extra review.
• Track exceptions, retest remediated assets, and close the item only after evidence is documented.
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.
