## What is CVE-2026-1058?

CVE-2026-1058 is a high-severity cross-site scripting vulnerability in Form Maker by 10Web – Mobile-Friendly Drag & Drop Contact Form Builder, published on 3 Feb 2026. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.

### Official description

The Form Maker plugin for WordPress is vulnerable to Stored Cross-Site Scripting via hidden field values in all versions up to, and including, 1.15.35. This is due to insufficient output escaping when displaying hidden field values in the admin submissions list. The plugin uses html_entity_decode() on user-supplied hidden field values without subsequent escaping before output, which converts HTML entity-encoded payloads back into executable JavaScript. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in the admin submissions view that will execute whenever an administrator accesses the submissions list.

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