CVE-2026-31150 Overview
CVE-2026-31150 is an Incorrect Access Control vulnerability discovered in Kaleris Yard Management System (YMS) version 7.2.2.1. This broken access control flaw allows authenticated attackers who possess only the shipping/receiving role to improperly access truck dashboard resources that should be restricted to higher-privileged users.
Critical Impact
Authenticated users with limited shipping/receiving privileges can view sensitive truck dashboard information, potentially exposing operational logistics data and compromising supply chain visibility controls.

Technical Details for CVE-2026-31150
Vulnerability Analysis
This vulnerability stems from improper implementation of role-based access control (RBAC) within the Kaleris YMS application. The system fails to adequately enforce authorization checks when users with the shipping/receiving role attempt to access truck dashboard resources. Under normal operation, truck dashboard functionality should be restricted to users with elevated privileges such as yard supervisors or fleet managers. However, the flawed access control logic permits lower-privileged authenticated users to bypass these restrictions.
The impact is primarily confidentiality-focused, as attackers can view unauthorized information but cannot modify data or disrupt system availability. This type of horizontal privilege escalation within the application could expose sensitive logistics data including truck locations, scheduling information, driver details, and operational metrics.
Root Cause
The root cause of CVE-2026-31150 is classified under CWE-284 (Improper Access Control). The application does not properly validate user role permissions before granting access to the truck dashboard resources. The authorization logic likely checks only for authenticated session status without verifying the specific role-based permissions required for dashboard access.
Attack Vector
An attacker must first obtain valid credentials for an account with the shipping/receiving role. Once authenticated, the attacker can directly navigate to or request truck dashboard endpoints that should be access-restricted. The network-accessible nature of this vulnerability means it can be exploited remotely by any authenticated user with the minimum required role, requiring no user interaction beyond the initial authentication.
The attack is straightforward to execute—authenticated users simply access dashboard URLs or API endpoints directly, and the application serves the restricted content without proper authorization validation. This could be accomplished through direct URL manipulation, API calls, or by modifying client-side navigation controls.
Detection Methods for CVE-2026-31150
Indicators of Compromise
- Unusual access patterns where shipping/receiving role accounts request truck dashboard resources
- Application logs showing successful dashboard resource retrievals by users with insufficient privileges
- Multiple rapid requests to dashboard endpoints from accounts that typically access only shipping/receiving functions
Detection Strategies
- Implement application-layer monitoring to flag dashboard access attempts by users with shipping/receiving roles
- Review web server and application logs for unauthorized access patterns to truck dashboard endpoints
- Deploy SIEM rules to correlate user role assignments with accessed resources and alert on mismatches
Monitoring Recommendations
- Enable detailed access logging for all dashboard resources with user role context
- Configure alerting for access control policy violations within the YMS application
- Conduct periodic access control audits comparing user roles to actual resource access patterns
How to Mitigate CVE-2026-31150
Immediate Actions Required
- Review and restrict access to truck dashboard resources to only authorized roles
- Audit all user accounts with shipping/receiving roles for suspicious access to dashboard resources
- Implement additional authorization checks at the application layer for sensitive dashboard endpoints
- Contact Kaleris support to inquire about available patches or security updates
Patch Information
No official vendor patch information has been published at this time. Organizations should monitor the Kaleris Yard Management solutions page for security advisories and updates. Additional technical details regarding this vulnerability can be found in the GitHub CVE Repository.
Workarounds
- Implement network segmentation to limit access to the YMS application from untrusted network segments
- Deploy a web application firewall (WAF) with rules to restrict dashboard endpoint access based on user session attributes
- Temporarily disable or restrict dashboard functionality for non-essential user roles until a patch is available
- Implement additional authentication factors for accessing sensitive dashboard resources
