CVE-2023-2220Public exploitNetwork attack vector

Script execution via unfiltered Object-typed form fields

Published Apr 21, 2023 · Updated Aug 2, 2024

Cross-site scripting in Dreamlu Mica 3.0.0 through 3.0.5 allows remote attackers to execute script through Object-typed form input. The Mica XSS filter does not sanitize a form field when an application endpoint declares that input field with Java's Object type. An application must expose such an endpoint, and a user must render the resulting content; exploitation runs attacker-controlled script in that user's browser context.
