Executive Summary:
A critical authentication bypass vulnerability has been identified in Kanboard project management software. This flaw allows an unauthenticated attacker to impersonate any user, including administrators, by sending a specially crafted request, granting them complete control over the application. This could lead to the theft of sensitive project data, system disruption, and unauthorized modifications.

Vulnerability Details

CVE-ID: CVE-2026-21881

Affected Software: Kanboard is project management software focused on Kanban Multiple Products

Affected Versions: Versions 1.2.48 and below

Vulnerability: The vulnerability exists in Kanboard instances where the REVERSE_PROXY_AUTH feature is enabled. The application is designed to delegate authentication to a trusted reverse proxy, which then passes the authenticated user's identity in an HTTP header (e.g., REMOTE_USER). However, the application fails to verify that these requests originate exclusively from the trusted proxy. A remote, unauthenticated attacker can bypass the proxy, connect directly to the Kanboard application, and inject a spoofed HTTP header to impersonate any valid user, granting them the full privileges of that user's account.

Business Impact

This vulnerability is rated as critical severity with a CVSS score of 9.1. Successful exploitation grants an attacker complete administrative control over the Kanboard application. This can lead to severe business consequences, including the compromise of confidential project information, theft of intellectual property, unauthorized modification or deletion of critical data, and disruption of project management workflows. The compromised system could also serve as a foothold for attackers to pivot and launch further attacks against the internal network.

Remediation Plan

Immediate Action: Update Kanboard is project management software focused on Kanban Multiple Products to the latest version (1.2.49 or newer), which contains the fix for this vulnerability. After patching, review application and web server access logs for any suspicious login activity or direct access attempts that may indicate prior exploitation.

Successful exploitation could lead to complete system compromise, data theft, and unauthorized modification of all managed data.

Vulnerability Details

CVE-ID: CVE-2026-21854

Affected Software: The Tarkov Data Manager is a tool to manage the Tarkov item Multiple Products

Affected Versions: All versions prior to the fixes released on 02 January 2025.

Vulnerability: The vulnerability is an authentication bypass located in the application's login endpoint. It stems from a combination of two weaknesses: a JavaScript prototype property access vulnerability (commonly known as Prototype Pollution) and the use of loose equality type coercion in the authentication logic. An unauthenticated attacker can send a specially crafted request, likely a JSON payload, to the login endpoint. This payload manipulates the JavaScript object's prototype, which in turn allows the attacker to trick the server-side authentication check that uses loose equality (e.g., == instead of ===), causing it to incorrectly validate the attacker's session and grant full administrative privileges without requiring any credentials.

Business Impact

This vulnerability is rated as critical severity with a CVSS score of 9.8. Exploitation by an unauthenticated attacker grants complete administrative control over the Tarkov Data Manager. This could result in catastrophic business consequences, including the theft, modification, or deletion of sensitive item data, disruption of services relying on this data, and reputational damage. An attacker with admin access could also potentially use the application as a foothold to launch further attacks against the underlying server and other connected systems within the network.

Remediation Plan

Immediate Action: The primary and most effective remediation is to update all instances of The Tarkov Data Manager to the latest version, which contains the security patches released on 02 January 2025. After patching, it is crucial to review access logs for any signs of compromise prior to the update, such as successful administrative logins from unknown IP addresses.

Immediate Action: Apply the security updates provided by the vendor across all affected products immediately. After patching, it is critical to review all dashboard permission configurations and audit access logs for any unauthorized or suspicious permission changes that may have occurred prior to the patch deployment.

Proactive Monitoring: Implement enhanced logging and monitoring for the dashboard permissions API. Security teams should look for patterns of unusual activity, such as a high volume of requests to the permissions endpoint from a single user, or attempts by non-administrative users to modify permissions for high-value dashboards. Alert on any successful permission change that was not associated with a corresponding authorized change request ticket.

Compensating Controls: If immediate patching is not feasible, implement the following compensating controls:

• Use a Web Application Firewall (WAF) to create rules that restrict access to the permissions API endpoint to only known administrative users or IP addresses.
• Temporarily disable self-service permission management features for non-administrative users if the application allows.
• Conduct a full audit of all user roles and dashboard permissions to identify and revoke any excessive or unauthorized privileges immediately.

Vulnerability Details

CVE-ID: CVE-2026-21675

Affected Software: iccDEV provides a set of libraries and tools for working with ICC color management Multiple Products

Affected Versions: Versions 2.3.1 and below

Vulnerability: The vulnerability is a Use After Free (UAF) condition within the CIccXform::Create() function of the iccDEV library. In vulnerable versions, a memory object (hint) is deallocated (freed) but a pointer to it is kept. Later, the program attempts to use this pointer, which now points to invalid memory. An attacker can exploit this by crafting a malicious file (such as an image with a specially designed ICC color profile) that, when processed by an application using the vulnerable library, manipulates memory to place malicious code in the freed location. Successful exploitation leads to arbitrary code execution in the context of the user running the application or a denial-of-service condition through an application crash.

Business Impact

This vulnerability is rated as critical severity with a CVSS score of 9.8. Successful exploitation could lead to a complete compromise of the system where the vulnerable software is running. An attacker could execute code remotely, allowing them to install malware, exfiltrate sensitive data, disrupt business operations, or use the compromised system as a pivot point to attack other internal network resources. The business risk is significant for any system that processes untrusted files using software dependent on the vulnerable iccDEV library, such as graphic design workstations, web servers that process image uploads, or document management systems.

Remediation Plan

Immediate Action:
Identify all systems and applications that utilize the iccDEV library and update them to the patched version 2.3.1.1 or later. Prioritize patching on internet-facing systems and critical workstations that process files from external sources. After patching, monitor for any signs of exploitation attempts and review relevant application and system logs for unusual activity preceding the update.

Proactive Monitoring:
Implement enhanced monitoring for applications that use the iccDEV library. Look for unusual application crashes, especially those related to file processing. Monitor for suspicious child processes spawning from the affected applications. Analyze network traffic for unexpected outbound connections from systems running the software, which could indicate a successful compromise. Review security logs for memory corruption errors or access violations tied to the vulnerable processes.

Compensating Controls:
If immediate patching is not feasible, implement the following controls to reduce risk:

• Restrict File Processing: Block or quarantine files from untrusted or external sources until they can be scanned in an isolated environment.
• Application Sandboxing: Run the affected applications in a sandbox or container to limit the impact of a potential exploit, preventing it from affecting the underlying operating system.
• Endpoint Detection and Response (EDR): Ensure EDR solutions are deployed and configured to detect and block anomalous process behavior and memory manipulation techniques commonly used in UAF exploits.
