Administrator-session script execution via stored tag title
Published Aug 25, 2023 · Updated Oct 2, 2024
Stored XSS in Badaso 2.9.7 allows remote authenticated users to execute scripts in an administrator's browser through a tag title. The Add Tag function stores the Title parameter without neutralizing injected HTML, then renders it when an administrator opens new-post or edit-post views. Editor access is required to save the payload, and administrator interaction triggers code in Badaso's origin, enabling access to or modification of data available to that session.
