We were using this tool, until we found a serious security breach. We reported this to the support team a week ago, and have not heard back from them ever since.

Honestly, if this kind of threat to the whole tool is not being taken seriously, I don´t want to use that tool anymore.

For the record, this is the message that went out to Gappeo.

"I hope this message finds you well. We have recently discovered a critical security breach in the ATS platform provided by your team that requires immediate attention.
The issue involves candidates who complete an assessment and exit the platform being able to re-enter and access all assessments taken by other candidates. This not only poses a significant threat to the confidentiality of our assessment process but also compromises the integrity of the platform and the fairness of candidate evaluations.

We kindly request your urgent investigation into this matter and a swift resolution to prevent further unauthorized access. Please let us know the steps you will take to address this and any interim measures we can implement to mitigate the risk while the issue is being resolved."
