Authelia takes security very seriously. We follow the rule of responsible disclosure, and we encourage the community to as well.
Join the Matrix Room and locate one of the maintainers. You can identify them as they are the room administrators. Alternatively you can just ask for one of the maintainers. Once you’ve made contact we ask you privately message the maintainer to communicate the vulnerability.
You can contact any of the maintainers for security vulnerability related issues by emailing firstname.lastname@example.org. This email is strictly reserved for security and vulnerability disclosure related matters. If you need to contact us for another reason please use Matrix or email@example.com.
