CVE-2026-101287: CWE-565 Reliance on cookies without validation and integrity checking in Diaple Stela
Description
Authentication bypass vulnerability in Stela, versions prior to 1.60.1, due to the use of a cookie named “authProcess” without validating its integrity. The application stores the user identifier (userId) and the status of the authentication process (validSteps) in this cookie and relies on these values—which can be modified by the client—to complete the login process. A remote attacker, without valid credentials or interaction from other users, could manipulate the cookie to bypass authentication checks and impersonate any account, including one with SUPER_ADMIN privileges. This would allow the attacker to obtain a valid JWT token with administrative privileges and compromise the confidentiality and integrity of the application.

Technical Analysis
The vulnerability arises from reliance on a client-modifiable cookie ('authProcess') that contains the userId and authentication status (validSteps) without integrity checks. An attacker can alter these values to bypass authentication controls remotely and gain unauthorized administrative access. This flaw affects Stela versions before 1.60.1 and enables compromise of confidentiality and integrity of the application.
Potential Impact
An unauthenticated remote attacker can bypass authentication and impersonate any user, including SUPER_ADMIN accounts. This leads to unauthorized access with administrative privileges and the ability to obtain valid JWT tokens, severely compromising the application's confidentiality and integrity.
