CVE-2025-15669: Unknown Bit Form

Medium severity, CVSS 4.8. EPSS: 0.2% chance of exploitation in the next 30 days.

The Bit Form WordPress plugin before 3.1.4 does not sanitise one of its conversational-form display settings before rendering it on the public-facing form, allowing high-privilege users (such as administrators, who do not hold the unfiltered_html capability on multisite) to store JavaScript that executes in the browser of any visitor who views the form.

Affected products

• Unknown Bit Form: before 3.1.4 (fixed in 3.1.4)
