CVE-2023-46503Public exploitNetwork attack vector

Browser script execution via unfiltered names

Published Oct 27, 2023 · Updated Sep 12, 2024

Reflected XSS in PwnCYN YXBOOKCMS 1.0.2 allows remote attackers to run script in a user's browser through reader or book names. The reader-management and book-input modules accept those names without filtering and reflect the input into executable page content. Exploitation requires a user to load the crafted response, and the resulting script executes within that user's browser context.
