CVE-2026-41574 WRITEUP CRITICAL WRITEUP
Nhost Vulnerable to Account Takeover via OAuth Email Verification Bypass
Nhost is an open source Firebase alternative with GraphQL. Prior to version 0.49.1, Nhost automatically links an incoming OAuth identity to an existing Nhost account when the email addresses match. This is only safe when the email has been verified by the OAuth provider. Nhost's controller trusts a profile.EmailVerified boolean that is set by each provider adapter. The vulnerability is that several provider adapters do not correctly populate this field they either silently drop a verified field the provider API actually returns (Discord), or they fall back to accepting unconfirmed emails and marking them as verified (Bitbucket). Two Microsoft providers (AzureAD, EntraID) derive the email from non-ownership-proving fields like the user principal name, then mark it verified. The result is that an attacker can present an email they don't own to Nhost, have the OAuth identity merged into the victim's account, and receive a full authenticated session. This issue has been patched in version 0.49.1.

CVE-2026-34200 WRITEUP HIGH WRITEUP
Nhost CLI MCP Server: Missing Inbound Authentication on Explicitly Bound Network Port
Nhost is an open source Firebase alternative with GraphQL. Prior to version 1.41.0, The Nhost CLI MCP server, when explicitly configured to listen on a network port, applies no inbound authentication and does not enforce strict CORS. This allows a malicious website visited on the same machine to issue cross-origin requests to the MCP server and invoke privileged tools using the developer's locally configured credentials. This vulnerability requires two explicit, non-default configuration steps to be exploitable. The default nhost mcp start configuration is not affected. This issue has been patched in version 1.41.0.
CVSS 7.5
CVE-2026-33221 WRITEUP MEDIUM WRITEUP
Nhost Storage Affected by MIME Type Spoofing via Trusted Client Content-Type Header in Storage Upload
Nhost is an open source Firebase alternative with GraphQL. Prior to version 0.12.0, the storage service's file upload handler trusts the client-provided Content-Type header without performing server-side MIME type detection. This allows an attacker to upload files with an arbitrary MIME type, bypassing any MIME-type-based restrictions configured on storage buckets. This issue has been patched in version 0.12.0.
