Detailsinfo

A vulnerability classified as critical has been found in Diaple Stela up to 1.60.0. This affects an unknown functionality. The manipulation of the argument authProcess with an unknown input leads to a improper authentication vulnerability. CWE is classifying the issue as CWE-287. When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

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.

The advisory is shared at incibe.es. This vulnerability is uniquely identified as CVE-2026-101287 since 09/28/2026. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details are known, but no exploit is available.

Upgrading to version 1.60.1 eliminates this vulnerability.
