CVE-2023-2507Public exploitNetwork attack vector

JavaScript execution via unvalidated deep-link data

Published Jul 15, 2023 · Updated Sep 24, 2025

Reflected XSS in CleverTap Cordova Plugin 2.6.2 allows remote attackers to execute JavaScript in Android apps via crafted deep links. The Android deep-link handler incorporates attacker-controlled URI text into the Cordova JavaScript path without neutralizing script syntax. Exploitation requires a browsable intent filter and user interaction with attacker-hosted content; injected script runs inside the affected app.
