CVE-2026-90787 in StudentManagement
Summary
by MITRE • 09/14/2026
A vulnerability was identified in Soarkey StudentManagement up to e08f7f1d5015af407aa4cca0ada3dea189b4937e. Affected is the function RegisterServlet.doPost of the file code/WebContent/register.html of the component Registration Workflow. Such manipulation of the argument level leads to improper privilege management. The attack can be launched remotely. The exploit is publicly available and might be used. This product does not use versioning. This is why information about affected and unaffected releases are unavailable. The project was informed of the problem early through an issue report but has not responded yet.

The identified vulnerability in Soarkey StudentManagement, specifically within the Registration Workflow component prior to commit e08f7f1d5015af407aa4cca0ada3dea189b4937e, represents a critical failure in access control mechanisms. The flaw resides in the RegisterServlet.doPost method located in code/WebContent/register.html and is triggered by manipulating the level argument during user registration. This manipulation allows an attacker to assign administrative or elevated privileges to unprivileged accounts without proper authorization checks. Such improper privilege management fundamentally undermines the security model of the application, as it permits users to escalate their access rights arbitrarily. The vulnerability aligns with CWE-269, which classifies Improper Privilege Management, and is also indicative of CWE-862, Missing Authorization, where the system fails to verify that a user has the necessary permissions for an action before executing it.
The operational impact of this flaw is severe due to its remote exploitability. An attacker can launch attacks from any network location without requiring prior authentication or physical access to the target system. The availability of public exploits significantly increases the risk landscape, as malicious actors do not need to develop custom tools to compromise the system. Once exploited, an adversary could gain full control over the student management database and application functionality. This level of access enables a range of destructive activities including data exfiltration, modification of academic records, injection of malware, or using the compromised server as a pivot point for further network intrusion. The situation is exacerbated by ATT&CK technique T1078, Valid Accounts, where attackers leverage legitimate credentials obtained through privilege escalation to maintain persistent access and evade detection mechanisms that rely on identifying anomalous login behaviors from unknown sources.
Compounding the severity of this vulnerability is the lack of versioning in the product release cycle. Without distinct version identifiers, it is impossible for administrators or security teams to determine which specific deployments are affected by this flaw. This absence of clear version control hinders effective patch management and risk assessment processes. Organizations relying on Soarkey StudentManagement cannot easily verify if their instance contains the vulnerable code unless they perform manual code audits against the known bad commit hash provided in the report. The project maintainers were notified early via an issue report but have not yet responded, leaving users without official guidance or patches to mitigate this risk. This delay places the burden of remediation entirely on the end-users and system administrators who must implement workarounds independently.
To mitigate these risks, immediate action is required from those operating affected instances. Since no patch has been released by the vendor, organizations should consider isolating the application behind a Web Application Firewall configured to block requests containing suspicious level parameter manipulations during registration attempts. Implementing strict input validation on the server side for all privilege-related fields can prevent client-side tampering from succeeding. Additionally, enabling comprehensive logging and monitoring for unusual account creation patterns or sudden changes in user roles can help detect exploitation attempts in real-time. Until a vendor-supplied fix is available, restricting public access to the registration endpoint or disabling new registrations entirely may be necessary to reduce the attack surface. Long-term solutions should include advocating for proper version control practices within the development lifecycle and ensuring that security reviews are integrated into the code commit process to prevent such logic flaws from reaching production environments.
