- Severity: CVSS 6.1 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial

- Published: 2023-06-03 · Updated: 2026-04-08

## Affected

- eyale-vc Contact Form Builder by vcita: through 4.10.3

## Description

The Contact Form Builder by vcita plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 4.10.3. This is due to missing nonce validation on the ls_parse_vcita_callback function. This makes it possible for unauthenticated attackers to modify the plugin's settings and inject malicious JavaScript via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. While the Cross-Site Scripting issue was patched in version 4.10.1, the plugin is still technically vulnerable to Cross-Site Request Forgery since a capability check but no nonce check was added in 4.10.2.
