Published Apr 11, 2022 · Updated Aug 2, 2024

Reflected XSS in Press Customizr Nimble Page Builder before 3.2.2 allows remote attackers to run script via preview-level-guid. The customize_messenger_channel endpoint returns the POST parameter in a page without sanitizing or context-appropriate escaping. Exploitation requires a victim to submit a crafted form and interact with the reflected element; script then runs in the site's browser origin.
