Details
As written in the advisory (Markdown source, shown as plain text).
### Background
NATS.io is a high performance open source pub-sub distributed communication technology, built for the cloud, on-premise, IoT, and edge computing.
The persistent storage feature, JetStream, has a management API which has many features, amongst which are backup and restore.
### Problem Description
Users with JetStream admin API access to restore one stream could restore to other stream names, impacting data which should have been protected against them.
### Affected Versions
Any version before v2.12.6 or v2.11.15
### Workarounds
If developers have configured users to have limited JetStream restore permissions, temporarily remove those permissions.
