CVE-2023-1159Network attack vector

Admin-level stored XSS via unsanitized service titles

Published Jun 2, 2023 · Updated Dec 20, 2024

Stored XSS in Ladela Interactive Bookly 21.7 allows remote authenticated users to inject scripts through crafted service titles. The createService path obtains the Service Title through getRequest and stores it without sanitizing embedded script, which later renders in a visitor's browser. Administrator privileges and either WordPress multisite or disabled unfiltered_html are required; successful exploitation runs attacker-controlled script in a user session.
