SCA: security update for @feathersjs/authentication-oauth (GHSA-wg9x-qfgw-pxhj)

critical Tenable Cloud Security Plugin ID 438621

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Feathersjs is a framework for creating web APIs and real-time applications with TypeScript or JavaScript.
 From 5.0.0 to before 5.0.42, an unauthenticated attacker can send a crafted GET request directly to
 /oauth/:provider/callback with a forged profile in the query string. The OAuth service's authentication
 payload has a fallback chain that reaches params.query (the raw request query) when Grant's session/state
 responses are empty. Since the attacker never initiated an OAuth authorize flow, Grant has no session to
 work with and produces no response, so the fallback fires. The forged profile then drives entity lookup
 and JWT minting. The attacker gets a valid access token for an existing user without ever contacting the
 OAuth provider. This vulnerability is fixed in 5.0.42. (CVE-2026-29792)

Solution

Update the @feathersjs/authentication-oauth library and its related packages to version 5.0.42 or later.
