## What is CVE-2026-103421?

CVE-2026-103421 is a medium-severity cross-site scripting vulnerability in amauric WPMobile.App – Android and iOS App Builder, published on 3 Oct 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

The WPMobile.App – Android and iOS App Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'REQUEST_URI (path segment after /android_json/search/)' parameter in all versions up to, and including, 11.84 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Exploitation requires the app's content mode to be configured as 'webview' (i.e., the 'speed' option is not set to '1'), which is a supported and still-shipped mode, though no longer the default.

Weakness: CWE-79 (Improper Neutralization of Input During Web Page Generation)
