CVE-2026-105392 in Django-Vue-Lyadmin
Summary
by MITRE • 10/06/2026
A vulnerability has been found in Lybbn Django-Vue-Lyadmin up to 3.2.12. The impacted element is an unknown function of the file backend/application/settings.py of the component JWT Signing. The manipulation of the argument SECRET_KEY leads to use of hard-coded cryptographic key
. Remote exploitation of the attack is possible. The exploit has been disclosed to the public and may be used. The project maintainer explains: "The issue with this key is described in the documentation. Developers need to manually change their keys before deployment."

A critical security vulnerability exists within Lybbn Django-Vue-Lyadmin, specifically affecting versions up through 3.2.12, centered on the JWT signing mechanism located in the backend application settings file. The core technical flaw involves the improper handling of the SECRET_KEY argument, which results in the utilization of a hard-coded cryptographic key rather than a dynamically generated or securely configured secret value known only to the deployment environment. This configuration error fundamentally undermines the integrity and confidentiality assurances provided by JSON Web Token authentication protocols, as it allows any party with knowledge of the default key to forge valid tokens for arbitrary users or administrative accounts.
The operational impact of this vulnerability is severe due to its remote exploitability. Since JWTs are commonly used for stateless session management in web applications, an attacker can leverage the known hard-coded secret to generate forged authentication tokens without needing prior access credentials. This capability effectively bypasses all intended access controls within the application, granting unauthorized users full administrative privileges or the ability to impersonate legitimate system administrators. The public disclosure of exploit code further exacerbates this risk by lowering the barrier for entry, enabling even attackers with limited technical expertise to compromise affected systems and potentially exfiltrate sensitive data or disrupt service availability through privilege escalation attacks.
From a classification perspective, this vulnerability aligns closely with CWE-798, which describes the use of hard-coded credentials, as well as CWE-321 regarding the use of a single key for multiple cryptographic operations when distinct keys are required for security isolation. In terms of offensive cybersecurity frameworks such as MITRE ATT&CK, this flaw facilitates techniques related to Credential Access and Defense Evasion, specifically allowing attackers to bypass authentication mechanisms by forging valid identity assertions that appear legitimate to the application backend due to the shared secret mismatch between expected secure practices and actual implementation.
To mitigate this risk immediately, developers must ensure that no default or hard-coded SECRET_KEY values are present in production deployments of Django-Vue-Lyadmin prior to version 3.2.13 or any subsequent patched releases. The project maintainer has explicitly stated that the issue stems from a documentation gap where users were expected to manually override these keys before deployment, but this reliance on manual intervention is insufficient for robust security hygiene. Organizations should implement automated configuration validation checks during their CI/CD pipelines to detect and reject deployments containing default cryptographic secrets. Furthermore, it is imperative to rotate any JWT signing keys that may have been exposed or used in conjunction with the vulnerable version across all affected environments to invalidate previously forged tokens and restore trust in the authentication system.
