CVE-2026-107810: Improper Link Resolution Before File Access

Nginx UI is a web user interface for the Nginx web server. From 2.0.0 until 2.5.0, internal/backup/restore.go extracts inner archives before applying the restorenginx and restorenginxui flags and permits symlinks targeting the live Nginx configuration path. An authenticated user who can create an...

CVE-2026-107809: Cross-Site Request Forgery (CSRF)

Nginx UI is a web user interface for the Nginx web server. From 2.0.0 until 2.5.0, AuthRequired accepts a browser-managed token cookie as an API credential after the front end stores the JWT in that cookie. Because management endpoints do not universally require a CSRF token or perform Origin or...

CVE-2026-107812: Download of Code Without Integrity Check

Nginx UI is a web user interface for the Nginx web server. From 2.0.0 until 2.5.0, the self-upgrade mechanism validates a downloaded binary only with a same-origin digest obtained from the same upgrade mirror. A compromised mirror or network attacker able to alter both responses can supply a...

CVE-2026-107811: Exposure of Sensitive Information to an Unauthorized Actor

Nginx UI is a web user interface for the Nginx web server. From 2.0.0 until 2.5.0, ordinary authenticated users can access /api/nodes and /api/nodes/:id, whose responses serialize the node token field. The same token is accepted as X-Node-Secret by AuthRequired and maps the request to initUser,...

CVE-2026-107804: Origin Validation Error

Nginx UI is a web user interface for the Nginx web server. From 2.2.0 until 2.6.0, the bundled reverse proxy does not preserve the external client identity used by Gin because the backend has no trusted proxy configuration.

CVE-2026-107805: Uncontrolled Resource Consumption

Nginx UI is a web user interface for the Nginx web server. From 2.5.0 until 2.6.0, the node-signature authentication path performs temporary file staging of an attacker-controlled request body and synchronizes it before validating the body digest and cryptographic signature. An unauthenticated...

CVE-2026-107806: Improper Control of Generation of Code

Nginx UI is a web user interface for the Nginx web server. From 2.3.8 until 2.5.0, an authenticated administrator with an active secure session can submit attacker-controlled portable backup key material and a matching manifest to POST /api/restore. The restore flow trusts the supplied key,...

CVE-2026-107813: Missing Authorization

Nginx UI is a web user interface for the Nginx web server. From 2.0.0 until 2.5.0, the api/cluster router exposes node and namespace mutation operations and cluster-wide Nginx reload or restart operations with AuthRequired but without RequireSecureSession. An authenticated OTP-enabled user...

Name of the Vulnerable Software and Affected Versions Nginx UI versions 2.0.0 through 2.4.x Description Nginx UI contains a cross-site request forgery CSRF flaw where the AuthRequired middleware accepts a browser-managed cookie named token as a valid API credential. Because management endpoints d...

CVE-2026-107808: Improper Authentication

Nginx UI is a web user interface for the Nginx web server. From 2.0.0 until 2.5.0, POST /api/login checks EnabledOTP but does not require a WebAuthn assertion when EnabledPasskey is true and no TOTP secret is configured. A passkey-only account is therefore issued a session after password...

This causes the backend to treat the local proxy pe...

CVE-2026-107807: Cleartext Storage of Sensitive Information

Nginx UI is a web user interface for the Nginx web server. From 2.0.0 until 2.5.0, Nginx UI accepts the Node.Secret master credential through the nodesecret query parameter in HTTP and WebSocket authentication paths instead of requiring the X-Node-Secret header. The credential can consequently...

SUSE CVE-2026-33031

Nginx UI is a web user interface for the Nginx web server. Prior to version 2.3.4, a user who was disabled by an administrator can use previously issued API tokens for up to the token lifetime. In practice, disabling a compromised account does not actually terminate that user's access, so an...

SUSE CVE-2026-34403
