What is CVE-2026-92767?

The Twenty20 Image Before-After plugin for WordPress allows authenticated users with contributor access and above to exploit a stored cross-site scripting vulnerability through the 'offset' shortcode attribute. Due to inadequate input sanitization and output escaping, attackers can inject malicious scripts into web pages. This poses a significant security risk as any user accessing the compromised page may unknowingly execute the injected scripts, leading to potential data breaches or site manipulation.

Affected Version(s)

Twenty20 Image Before-After 0 <= 2.0.5
