CVE-2025-62049 identifies a missing authorization vulnerability in the Stylemix Cost Calculator Builder plugin, a tool used primarily in WordPress environments to create cost estimation calculators. The vulnerability affects all versions up to and including 3.5.32. Missing authorization means that certain sensitive operations or data accessible through the plugin’s interface do not properly verify whether the requester has the necessary permissions. This flaw allows unauthenticated remote attackers to perform actions or access information that should be restricted, potentially leading to unauthorized data disclosure or limited data manipulation. The CVSS 3.1 base score is 6.5, reflecting a medium severity with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), and impacts on confidentiality and integrity but not availability (C:L/I:L/A:N). No known exploits have been reported in the wild as of the publication date. The vulnerability’s impact is primarily on confidentiality and integrity, as attackers could access or alter data managed by the plugin without authorization. Since the plugin is commonly used in e-commerce or service websites for cost calculations, unauthorized access could lead to manipulation of pricing or exposure of sensitive business data. The lack of authentication requirement and network accessibility make this vulnerability easier to exploit. However, the absence of availability impact and the medium severity score indicate that the threat is serious but not critical. The vulnerability was published on November 6, 2025, and no patches or mitigations were linked at the time, emphasizing the need for vendor response and user vigilance.

For European organizations, the impact of CVE-2025-62049 can be significant in sectors relying on the Stylemix Cost Calculator Builder plugin for customer-facing pricing or cost estimation services. Unauthorized access could lead to exposure of sensitive pricing models or business logic, potentially harming competitive advantage and customer trust. Integrity impacts might allow attackers to manipulate cost calculations, leading to financial loss or reputational damage. Although availability is not affected, the confidentiality and integrity breaches could trigger compliance issues under GDPR if personal or business data is exposed or altered. Organizations in e-commerce, professional services, or any sector using this plugin should consider the risk of unauthorized data access and manipulation. The medium severity suggests that while the threat is not immediately critical, it requires prompt attention to prevent exploitation, especially given the ease of exploitation without authentication or user interaction.

1. Monitor Stylemix’s official channels for patch releases addressing CVE-2025-62049 and apply updates immediately upon availability. 2. Until patches are released, restrict network access to the plugin’s administrative endpoints using web application firewalls (WAFs), IP whitelisting, or VPN access controls to limit exposure to trusted users only. 3. Implement strict access control policies on the WordPress environment, ensuring that only authorized administrators have plugin management privileges. 4. Conduct regular security audits and log monitoring focused on unusual access patterns or unauthorized attempts to interact with the Cost Calculator Builder plugin. 5. Consider temporarily disabling or removing the plugin if it is not critical to business operations until a secure version is available. 6. Educate web administrators about the risks of missing authorization vulnerabilities and the importance of timely patching and access restrictions. 7. Use security plugins or endpoint detection tools capable of detecting exploitation attempts targeting this vulnerability.
