CVE-2025-1031 identifies an authorization bypass vulnerability in the SoliClub software developed by Utarit Informatics Services Inc., affecting versions from 5.2.4 up to but not including 5.3.7. The vulnerability is classified under CWE-639, which involves authorization bypass through user-controlled keys. Specifically, the software fails to properly validate or restrict access based on a key parameter that users can manipulate. This flaw allows attackers to bypass intended authorization controls and misuse functionality, potentially accessing sensitive information without proper permissions. The CVSS v3.1 score is 7.5 (high), reflecting a network attack vector with low attack complexity, no privileges required, no user interaction, and a high impact on confidentiality. The vulnerability does not affect integrity or availability. Although no known exploits are currently reported in the wild, the ease of exploitation and the lack of authentication requirements make it a significant risk. The issue was reserved in early 2025 and published in December 2025, indicating recent discovery and disclosure. The absence of patch links suggests that a fix may be forthcoming or that users must upgrade to version 5.3.7 or later to remediate the issue. Organizations relying on SoliClub for their operations must prioritize addressing this vulnerability to prevent unauthorized data exposure.

For European organizations, the primary impact of CVE-2025-1031 is unauthorized access to sensitive data managed by SoliClub, leading to potential data breaches and loss of confidentiality. This can undermine trust, violate data protection regulations such as GDPR, and result in financial and reputational damage. Since the vulnerability does not affect data integrity or system availability, operational disruption is less likely. However, the exposure of confidential information can have cascading effects, including intellectual property theft or exposure of personal data. The fact that exploitation requires no authentication or user interaction increases the risk of automated attacks and broad exploitation. Organizations in sectors such as finance, healthcare, and government that handle sensitive information and use SoliClub are particularly vulnerable. The lack of known exploits currently provides a window for proactive mitigation before widespread attacks occur.

1. Upgrade SoliClub to version 5.3.7 or later as soon as the patch is available to ensure the authorization bypass vulnerability is fixed. 2. Until patching is possible, implement strict network-level access controls to restrict SoliClub access only to trusted internal users and systems. 3. Conduct a thorough review of access control policies within SoliClub, focusing on parameters that can be user-controlled, and apply additional validation or filtering to prevent unauthorized manipulation. 4. Monitor logs and network traffic for unusual access patterns or attempts to exploit authorization mechanisms. 5. Employ web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the vulnerable key parameters. 6. Educate administrators and users about the vulnerability and encourage prompt reporting of anomalies. 7. Coordinate with Utarit Informatics Services Inc. for timely updates and security advisories. 8. Consider implementing multi-factor authentication and enhanced session management to reduce risk exposure from compromised credentials or sessions.
