CVE-2023-2507: CleverTap Cordova Plugin 2.6.2 - Reflected XSS

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.

Security readout for executives and security teams

Plain-English summary

CVE-2023-2507 is a reflected XSS flaw in CleverTap Cordova Plugin 2.6.2. A malicious deep link could cause JavaScript execution inside an affected mobile app. The business risk is highest where the app processes sensitive user data or trusted workflows through that plugin.

Executive priority

Treat this as urgent for any production mobile app using version 2.6.2. The flaw can affect user data confidentiality and transaction integrity, but exploitation requires a user to open a malicious deep link and active exploitation is not evidenced here.

Technical view

The plugin did not correctly validate data received from deep links before use, enabling CWE-79 reflected XSS. The CVSS 3.1 score is 9.3 with network attack vector, low complexity, no privileges, required user interaction, changed scope, and high confidentiality and integrity impact.

Likely exposure

Exposure appears limited to applications that embed CleverTap Cordova Plugin version 2.6.2 and can be opened through deep links influenced by an attacker. The source bundle marks other versions as unaffected by default but does not enumerate every downstream application build.

Exploitation context

Sources describe remote exploitation through a specially constructed deep link requiring user interaction. The CVE is not listed as KEV in the provided bundle, and no cited source here confirms active exploitation in the wild.

Researcher notes

Focus analysis on dependency versioning, build provenance, and deep-link entry points. The public evidence supports affected version 2.6.2 and patch reference 2.7.0, but does not provide broad exploitation telemetry or detailed downstream application impact.

Mitigation direction

  • Upgrade affected apps from CleverTap Cordova Plugin 2.6.2 to the 2.7.0 patched release.
  • Check CleverTap release notes and vendor guidance before relying on compensating controls.
  • Prioritize rebuild and redeployment for apps handling authentication, payments, or sensitive customer data.
  • Review app deep-link handling for untrusted input assumptions around the plugin boundary.

Validation and detection

  • Inventory Cordova package manifests and lockfiles for CleverTap Cordova Plugin version 2.6.2.
  • Confirm whether affected app builds register deep links processed through the CleverTap plugin.
  • Verify remediated builds include CleverTap Cordova Plugin 2.7.0 or a later non-affected version.
  • Review mobile security test evidence for deep-link input handling without reproducing exploit payloads.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
