CVE-2025-11265Network attack vector

Contributor-level stored XSS via misselected sanitization callbacks

Published Nov 18, 2025 · Updated Nov 18, 2025

Stored cross-site scripting in VK All in One Expansion Unit 9.112.1 and earlier allows remote authenticated users to inject scripts via CTA fields. The CTA save function looks up sanitization callbacks in $custom_field_name instead of $custom_field_options, so the vkExUnit_cta_url and vkExUnit_cta_button_text values are stored without the intended filtering. Contributor-level access is required to plant the payload, which executes in a user’s browser when an affected page is opened.
