CVE-2023-6767Network attack vector

Stored XSS via unsanitized guest name

Published Dec 13, 2023 · Updated Nov 21, 2024

Cross-site scripting in SourceCodester Wedding Guest e-Book 1.0 allows remote attackers to inject script through the guest name field. The /endpoint/add-guest.php handler accepts the name parameter without neutralizing script markup before saved guest entries are rendered. Execution requires a user to view the affected guest list, and the resulting script runs within the application's browser origin.
