AI-suggested
Upgrade Nuxt to version 4.6.3 or later where this vulnerability is fixed. Alternatively, ensure that development servers are not exposed beyond localhost and configure explicit appSecrets for development environments to prevent exposure. No additional action is required for production builds as they are not affected.
Description
A vulnerability in Nuxt versions 4.6.0 through 4.6.2 allows an attacker with direct HTTP access to a development server to retrieve a generated appSecret file. This secret can be used to derive session passwords and forge session cookies, potentially compromising session integrity. The issue is limited to development servers bound to localhost and does not affect production builds or servers with explicitly configured secrets. The vulnerability is fixed in version 4.6.3.
