Kerentanan Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') pada bookstackapp bookstack. Skor CVSS 3.1 8.7 (High) menurut NVD.

Deskripsi (NVD)

In BookStack before version 0.30.4, a user with permissions to edit a page could add an attached link which would execute untrusted JavaScript code when clicked by a viewer of the page. Dangerous content may remain in the database after this update. If you think this could have been exploited the linked advisory provides a SQL query to test. As a workaround, page edit permissions could be limited to only those that are trusted until you can upgrade although this will not address existing exploitation of this vulnerability. The issue is fixed in version 0.30.4.
