Summary

Self Cross-Site Scripting (Self-XSS) vulnerability in the RD Station Conversas chat feature. The vulnerability lies in the ‘name’ parameter of the initialisation process due to incorrect sanitisation of user-supplied input. Exploitation allows specially crafted JavaScript code to be injected, which is executed within the context of the user’s own session who provides the payload. The demonstrated impact is limited to the user who enters and executes the payload.
