CVE-2025-62049 identifies a missing authorization vulnerability in the Stylemix Cost Calculator Builder plugin, affecting versions up to and including 3.5.32. This plugin is commonly used in WordPress environments to create customizable cost calculators for websites, often in e-commerce or service-oriented businesses. The vulnerability arises because the plugin fails to enforce proper authorization checks on certain actions or endpoints, allowing unauthenticated remote attackers to perform operations that should be restricted. According to the CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N), the attack can be executed remotely over the network without any privileges or user interaction, making exploitation relatively straightforward. The impact primarily affects confidentiality and integrity, potentially allowing unauthorized access to sensitive data or unauthorized modification of calculator configurations or outputs. However, availability is not impacted. No known public exploits or active exploitation campaigns have been reported as of the publication date, but the vulnerability’s presence in a widely used plugin increases the risk of future exploitation. The lack of vendor patches at the time of disclosure necessitates immediate attention from administrators to implement interim controls and monitor for suspicious activities. The vulnerability is significant because it undermines the trustworthiness of cost calculations presented to end users, which could lead to financial discrepancies or reputational damage for affected organizations.

For European organizations, the missing authorization vulnerability could lead to unauthorized disclosure or manipulation of cost calculation data, impacting business operations and customer trust. E-commerce platforms and service providers relying on the Cost Calculator Builder plugin may experience data integrity issues, such as altered pricing or cost estimates, which could result in financial losses or legal liabilities. Confidential information related to pricing strategies or client data might be exposed to attackers, potentially violating data protection regulations like GDPR. Although availability is not affected, the integrity and confidentiality impacts can disrupt business processes and damage brand reputation. The ease of exploitation without authentication increases the risk, especially for organizations with publicly accessible WordPress sites using this plugin. European entities with limited security monitoring or delayed patch management are particularly vulnerable. The absence of known exploits currently provides a window for proactive mitigation, but the threat landscape could evolve rapidly given the plugin’s popularity.

1. Monitor Stylemix’s official channels for security patches addressing CVE-2025-62049 and apply updates immediately upon release. 2. Until patches are available, restrict access to the Cost Calculator Builder’s administrative interfaces using IP whitelisting, VPNs, or web application firewalls (WAFs) to limit exposure. 3. Implement strict role-based access controls within WordPress to minimize the number of users who can interact with the plugin’s settings. 4. Conduct regular audits of plugin configurations and logs to detect unauthorized changes or access attempts. 5. Employ security plugins or WAF rules that can detect and block suspicious requests targeting the plugin endpoints. 6. Educate site administrators about the risks of unauthorized access and encourage prompt reporting of anomalies. 7. Consider temporarily disabling or replacing the plugin if immediate patching is not feasible and the risk is deemed high. 8. Ensure comprehensive backups are maintained to enable recovery from potential data integrity compromises.
