CVE-2025-9902 is an authorization bypass vulnerability classified under CWE-639, affecting the QRMenu software developed by AKIN Software Computer Import Export Industry and Trade Co. Ltd. The vulnerability exists in versions up to 1.05.12, prior to the patch dated 05.09.2025. It stems from the software's failure to properly validate or restrict user-controlled keys used in authorization processes. This flaw allows an unauthenticated attacker to bypass access controls and gain unauthorized privileges within the application, leading to privilege abuse. The vulnerability is remotely exploitable over the network without requiring any user interaction or prior authentication, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). The impact primarily affects confidentiality, as attackers can access sensitive information or functions they should not be authorized to use, though integrity and availability remain unaffected. The CVSS v3.1 base score of 7.5 reflects the high severity due to ease of exploitation and potential data exposure. No public exploits or active exploitation campaigns have been reported to date, but the vulnerability's nature makes it a significant risk. QRMenu is typically used in digital menu and ordering systems, which may be integrated into hospitality, retail, or trade environments. The lack of a patch link suggests that remediation is pending or must be obtained directly from the vendor. Organizations should monitor vendor communications closely and prepare to apply updates promptly once available.

For European organizations, the primary impact of CVE-2025-9902 lies in unauthorized access to sensitive data or privileged functions within QRMenu deployments. This could lead to exposure of customer information, internal business data, or manipulation of ordering processes, potentially undermining trust and causing regulatory compliance issues, especially under GDPR. Since the vulnerability allows remote exploitation without authentication, attackers can operate stealthily, increasing the risk of data breaches. Industries such as hospitality, retail, and trade that utilize QRMenu for digital menus or ordering systems are particularly vulnerable. The confidentiality breach could result in financial losses, reputational damage, and legal consequences. While integrity and availability are not directly impacted, the unauthorized access could be leveraged as a foothold for further attacks within the network. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, as attackers may develop exploits rapidly once the vulnerability becomes widely known.

1. Monitor AKIN Software vendor channels for official patches addressing CVE-2025-9902 and apply them immediately upon release. 2. Until patches are available, implement network-level access controls to restrict exposure of QRMenu services to trusted internal networks only. 3. Employ application-layer firewalls or intrusion prevention systems capable of detecting anomalous requests targeting authorization mechanisms. 4. Conduct thorough access reviews and tighten permissions within QRMenu to minimize privilege levels assigned to users and services. 5. Enable detailed logging and continuous monitoring of QRMenu access and authorization events to detect potential abuse attempts early. 6. Consider deploying multi-factor authentication (MFA) around administrative interfaces or sensitive functions if supported by QRMenu. 7. Educate staff about the risks of unauthorized access and establish incident response plans specific to QRMenu-related breaches. 8. Segment networks to isolate QRMenu systems from critical infrastructure to limit lateral movement in case of compromise.
