# CVE-2026-104926: CVE-2026-104926 Status: published. Published: 2026-10-31. Updated: 2026-11-01. The WooCommerce Extra Product Options Pro plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the '_start / _end' parameter in all versions up to, and including, 3.3.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. This vulnerability is only exploitable on product pages where a Date & Time Range Picker extra field is configured, though the required field name is visible in the product page source and requires no prior knowledge to discover. ## Remediation No remediation reported in collected sources ## Affected products and versions Not reported in collected sources. ## Severity and prioritization - CVSS 3.1: 6.1 (medium); CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N; source: NVD: security@wordfence.com - CISA KEV: No listing in collected sources - EPSS: Not available - SSVC: exploitation none; automatable no; technical impact partial; source NVD SSVC: 134c704f-9b21-4f2e-91b3-4a467353bcc0 - Weaknesses: CWE-79 ## Exploit evidence No exploit evidence in collected sources.
