We are aware of a security issue involving eMudhra, a third-party certificate authority used to verify secure internet connections. Our security and engineering teams are assessing potential exposure and proactively updating affected software and certificate bundles across our services and applications.

At this time, we have not identified evidence that Notion has been compromised in connection with this issue. This work is a preventative security measure, rather than a response to a service outage.

We’re taking precautionary steps to update affected certificate-validation components and block trust in the affected certificates where needed.
