CyberRota Analysis
AI-GeneratedThe vulnerability in Postiz allows unauthenticated remote attackers to exploit improper path handling, enabling them to read any file accessible by the application process, including sensitive configuration data such as JWT signing secrets and database connection strings. This critical flaw can lead to the creation of non-expiring session tokens, allowing attackers to impersonate any user, including administrators, without needing a password. Organizations using Postiz should prioritize immediate remediation to protect against potential unauthorized access and data breaches.

Original NVD Description
Postiz is an open-source social media scheduling tool. The route that serves locally stored media joins URL-supplied path segments onto the upload directory and streams the file without normalising the path or confining it to that directory, and the route requires no authentication. Raw dot-segments are collapsed before routing, but URL-encoded separators survive route matching and are decoded only once they reach the handler, restoring the traversal at the filesystem call. An unauthenticated remote attacker can therefore read any file readable by the application process, including the process environment, which exposes the JWT signing secret, the database connection string, and connected provider and billing secrets. Because session tokens are signed with that secret and carry no expiry, this allows forging a non-expiring session as any user, including an administrator, without a password.
