CVE-2025-31063 is a medium-severity vulnerability classified under CWE-862 (Missing Authorization) affecting the redqteam Wishlist product up to version 2.1.0. The vulnerability arises from incorrectly configured access control mechanisms, allowing users with limited privileges (PR:L - Privileges Required: Low) to perform actions or access resources without proper authorization checks. Specifically, the flaw is an access control weakness where the system fails to verify whether a user is authorized to perform certain operations, potentially enabling privilege escalation or unauthorized modification of wishlist data. The CVSS 3.1 base score is 4.3, reflecting a network attack vector (AV:N), low attack complexity (AC:L), requiring low privileges (PR:L), no user interaction (UI:N), unchanged scope (S:U), no confidentiality impact (C:N), limited integrity impact (I:L), and no availability impact (A:N). No known exploits are currently reported in the wild, and no patches have been published yet. The vulnerability was reserved in March 2025 and published in May 2025, indicating recent discovery and disclosure. The absence of patches suggests that affected organizations should prioritize mitigation and monitoring until fixes are available.

For European organizations using the redqteam Wishlist product, this vulnerability could lead to unauthorized modification of wishlist data or related information, potentially undermining data integrity and trustworthiness of the system. While confidentiality and availability are not directly impacted, the integrity compromise could affect business processes relying on accurate wishlist data, such as e-commerce personalization, inventory forecasting, or customer engagement strategies. The low privilege requirement means that even users with limited access could exploit this flaw, increasing the risk of insider threats or exploitation by attackers who have gained minimal access. Organizations in sectors with high reliance on e-commerce platforms, retail, or customer data management may experience operational disruptions or reputational damage if attackers manipulate wishlist contents or related features. The lack of known exploits reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits once the vulnerability details become widely known.

European organizations should implement strict access control reviews and enforce the principle of least privilege within their Wishlist deployments. Until official patches are available, administrators should audit user roles and permissions to ensure no excessive privileges are granted. Employing Web Application Firewalls (WAFs) with custom rules to detect and block unauthorized access attempts targeting wishlist functionalities can provide a temporary protective layer. Monitoring and logging access to wishlist-related endpoints should be enhanced to detect anomalous activities indicative of exploitation attempts. Additionally, organizations should engage with redqteam for updates on patch releases and apply them promptly once available. Conducting internal penetration testing focused on access control mechanisms can help identify similar weaknesses proactively. Finally, educating users about the risks of privilege misuse and enforcing strong authentication measures can reduce the likelihood of exploitation.
