CVE-2023-5119: Incsub Forminator

Medium severity, CVSS 4.8. EPSS: 0.5% chance of exploitation in the next 30 days.

The Forminator WordPress plugin before 1.27.0 does not properly sanitize the redirect-url field in the form submission settings, which could allow high-privilege users such as an administrator to inject arbitrary web scripts even when the unfiltered_html capability is disallowed (for example in a multisite setup).

Affected products

• Incsub Forminator: before 1.27.0 (fixed in 1.27.0)
