Thanks for reaching out and I appreciate your question to allow us to work on a fix in private.

The most direct way to report such issues to us is by creating a confidential GitLab issue. You can do that on this page, and by making sure that the "This issue is confidential and should only be visible to team members with at least Reporter access." checkbox is checked, which makes it confidential.

Alternatively, you can send an email with further details to or (see and we'll handle it from there. Ideally, the subject should indicate that it's about a security vulnerability.
