CVE-2026-1195 identifies a security weakness in the MineAdmin software, specifically in versions 1.x and 2.x, affecting the JWT Token Handler component's refresh function located at /system/refresh. The vulnerability stems from insufficient verification of data authenticity, which means that the system does not adequately validate the integrity or origin of JWT tokens during the refresh process. This flaw could allow a remote attacker to manipulate or forge JWT tokens, potentially bypassing authentication or authorization mechanisms. The attack vector is network-based (AV:N), requiring low privileges (PR:L) but no user interaction (UI:N). The complexity of the attack is high (AC:H), indicating that exploitation requires advanced skills or specific conditions. The impact on confidentiality, integrity, and availability is limited (VC:L, VI:L, VA:L), resulting in a low CVSS 4.0 score of 2.3. Despite the availability of a public exploit, no known active exploitation in the wild has been reported. The vendor was notified early but has not issued any response or patch, leaving users without an official fix. This vulnerability highlights the importance of robust token validation in authentication workflows to prevent unauthorized access or privilege escalation.

For European organizations using MineAdmin 1.x or 2.x, this vulnerability poses a risk of unauthorized access or token manipulation, potentially allowing attackers to impersonate users or escalate privileges within affected systems. Although the impact is assessed as low due to the high complexity and limited exploitability, sensitive environments relying on MineAdmin for critical operations could face integrity and confidentiality risks if exploited. The lack of vendor response and absence of patches increase exposure duration, requiring organizations to rely on alternative mitigations. The potential for remote exploitation without user interaction means that exposed MineAdmin instances accessible over the network are at risk. However, the low CVSS score and no known active exploitation suggest the immediate threat level is limited. Nonetheless, organizations should not dismiss the vulnerability, especially those in regulated sectors or handling sensitive data, as token manipulation could facilitate further attacks or data breaches.

Given the absence of official patches, European organizations should implement compensating controls to mitigate this vulnerability. These include restricting network access to MineAdmin instances by enforcing strict firewall rules and VPN-only access to reduce exposure to remote attackers. Organizations should monitor authentication logs for unusual token refresh activities or anomalies indicative of token forgery attempts. Employing Web Application Firewalls (WAFs) with custom rules to detect and block malformed or suspicious JWT tokens can provide an additional layer of defense. Where possible, upgrading to newer versions of MineAdmin that may address this issue or migrating to alternative solutions with robust token validation is advisable. Implementing multi-factor authentication (MFA) can reduce the risk of unauthorized access even if token manipulation occurs. Regular security assessments and penetration testing focusing on authentication mechanisms will help identify exploitation attempts. Finally, organizations should maintain close monitoring of vendor communications for any future patches or advisories.
