CVE-2026-1619 identifies an authorization bypass vulnerability categorized under CWE-639 (Authorization Bypass Through User-Controlled Key) in Universal Software Inc.'s FlexCity/Kiosk product. The vulnerability affects versions starting from 1.0 up to but not including 1.0.36. The root cause is the improper validation and handling of user-controlled keys, which are trusted identifiers used by the system to enforce authorization policies. An attacker with low-level privileges (PR:L) can manipulate these keys remotely over the network (AV:N) without requiring user interaction (UI:N) to bypass authorization checks. This bypass allows unauthorized access to sensitive functions or data, leading to a high impact on confidentiality and integrity, with a lesser impact on availability. The vulnerability scope is unchanged (S:U), meaning the exploit affects resources accessible to the same user or system context. The CVSS v3.1 base score is 8.3, indicating a high-severity issue. No patches are currently linked, and no known exploits have been reported in the wild, but the vulnerability is publicly disclosed and should be treated as a significant risk. The vulnerability is particularly concerning for environments where FlexCity/Kiosk is used for public access or critical operational tasks, as attackers could escalate privileges or access restricted data by exploiting this flaw.

For European organizations, this vulnerability poses a significant risk especially in sectors relying on Universal Software Inc.'s FlexCity/Kiosk systems, such as public service kiosks, transportation hubs, or municipal infrastructure. Exploitation could lead to unauthorized data access, manipulation of kiosk functions, or privilege escalation, potentially resulting in data breaches, disruption of services, or unauthorized transactions. Confidentiality and integrity of sensitive information handled by these kiosks could be severely compromised. The limited availability impact suggests service disruption is less likely but cannot be ruled out if attackers leverage the bypass to cause operational issues. Organizations in Europe with public-facing kiosks or integrated systems using FlexCity/Kiosk should consider this vulnerability a priority due to the ease of remote exploitation and the high potential impact on critical services and citizen data privacy.

1. Monitor Universal Software Inc. communications closely for official patches or updates addressing CVE-2026-1619 and apply them immediately upon release. 2. Until patches are available, implement strict network segmentation and firewall rules to restrict access to FlexCity/Kiosk systems only to trusted internal networks and authorized personnel. 3. Enforce strong authentication and authorization policies around kiosk management interfaces to reduce the risk of privilege escalation. 4. Conduct thorough access logging and real-time monitoring for anomalous activities indicative of authorization bypass attempts. 5. Review and harden configuration settings related to key management and trusted identifiers within the FlexCity/Kiosk environment. 6. Consider deploying application-layer firewalls or intrusion detection systems capable of detecting unusual key manipulation patterns. 7. Educate operational staff about the risks and signs of exploitation to enable rapid incident response. 8. Evaluate alternative kiosk solutions or additional compensating controls if patching is delayed or not feasible in the short term.
