CVE-2025-64276 identifies a missing authorization vulnerability in Ays Pro Survey Maker, a survey creation and management software product. The flaw exists in versions up to and including 5.1.9.4, where access control mechanisms are incorrectly configured, allowing users with limited privileges to access resources or perform actions beyond their authorization scope. Specifically, the vulnerability enables privilege-leveled attackers (PR:L) to bypass authorization checks without requiring any user interaction (UI:N). The attack vector is network-based (AV:N), meaning exploitation can occur remotely over the network. The vulnerability impacts confidentiality (C:H) but does not affect integrity or availability. This suggests that sensitive survey data could be exposed to unauthorized users, potentially leading to data leaks or privacy violations. The vulnerability does not require elevated privileges beyond limited user rights, making it easier to exploit than vulnerabilities requiring administrative access. No public exploits or active exploitation campaigns have been reported to date. The lack of patches at the time of publication indicates that organizations must rely on interim mitigations until official fixes are released. The vulnerability highlights the importance of correctly implementing access control and authorization checks in web applications, especially those handling sensitive or personal data such as survey responses.

For European organizations, the primary impact of CVE-2025-64276 is the unauthorized disclosure of sensitive survey data, which may include personal information protected under GDPR. This exposure can lead to privacy violations, regulatory penalties, and reputational damage. Organizations in sectors such as market research, healthcare, education, and government that rely on Survey Maker for collecting and managing survey data are particularly vulnerable. The breach of confidentiality could undermine trust with customers and stakeholders. Since the vulnerability does not affect data integrity or availability, operational disruptions are less likely, but the data exposure risk remains significant. Additionally, unauthorized access to survey data could be leveraged for further social engineering or targeted attacks. European entities must consider the legal implications of data breaches under stringent data protection laws and the potential for cross-border data privacy issues. The medium CVSS score reflects a moderate but non-negligible risk that requires timely mitigation to prevent exploitation.

1. Immediately review and restrict user privileges within Ays Pro Survey Maker to the minimum necessary, ensuring that no unnecessary elevated access is granted. 2. Conduct a thorough audit of access control configurations and permissions to identify and remediate any misconfigurations. 3. Monitor application logs and network traffic for unusual access patterns or unauthorized attempts to access survey data. 4. Implement network segmentation and firewall rules to limit access to the Survey Maker application to trusted users and systems only. 5. Engage with the vendor to obtain patches or updates addressing this vulnerability as soon as they become available and apply them promptly. 6. If patches are not yet available, consider deploying web application firewalls (WAFs) with custom rules to detect and block unauthorized access attempts. 7. Educate users and administrators on the importance of access control hygiene and the risks associated with privilege misuse. 8. Regularly back up survey data securely to enable recovery in case of any data compromise. 9. Review and update incident response plans to include scenarios involving unauthorized data access through application vulnerabilities.
