CVE-2026-42238 Unauthenticated Remote Code Execution via Backup Restore in nginx-ui

Nginx UI is a web user interface for the Nginx web server. Prior to version 2.3.8, nginx-ui exposes a backup restore endpoint POST /api/restore that is completely unauthenticated during the first 10 minutes after process startup on any fresh installation. An unauthenticated remote attacker can...

CVE-2026-42220 nginx-ui: Authenticated settings disclosure exposes node.secret and enables trusted-node authentication abuse, backup exfiltration, and restore-based nginx-ui state rollback

Nginx UI is a web user interface for the Nginx web server. Prior to version 2.3.8, an authenticated user can call GET /api/settings and retrieve sensitive configuration values, including node.secret. The same node.secret is accepted by AuthRequired through the X-Node-Secret header or nodesecret...

CVE-2026-42220

Nginx UI (nginx-ui) prior to version 2.3.8 exposes a vulnerability where an authenticated user can call GET /api/settings to retrieve sensitive values, including node.secret. The node.secret is accepted by AuthRequired() via the X-Node-Secret header (or node_secret query parameter), allowing the ...

Incus has Nil Dereferences on Restore via Malformed YAML

Summary Details It was found that backup.GetInfo trusts the inline backup/index.yaml config when present and only falls back to parsing the legacy backup/container/backup.yaml file if result.Config == nil. As a result, an archive can carry a valid inline config that passes the initial import...

GHSA-67WX-R9XR-X75X Incus has Unbounded YAML Metadata Decode via Parsing

Summary User provided image and backup tarballs would be unpacked and YAML files parsed without any size restrictions. This was making it easy for an authenticated user to provide a crafted image or backup tarball that when parsed by Incus would lead to a very large YAML document being loaded int...
