CVE-2025-47541 is a high-severity vulnerability classified under CWE-201, which involves the insertion of sensitive information into sent data within the WPFunnels Mail Mint product. This vulnerability affects versions up to 1.17.7 of Mail Mint. The core issue is that sensitive data embedded in the application or its processes is inadvertently included in outgoing data transmissions. This can lead to unauthorized disclosure of confidential information without requiring any authentication or user interaction. The CVSS 3.1 base score of 7.5 reflects a network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction needed (UI:N), unchanged scope (S:U), and high impact on confidentiality (C:H) with no impact on integrity or availability (I:N, A:N). Essentially, an attacker can remotely exploit this vulnerability to retrieve sensitive embedded data, potentially including credentials, personal information, or configuration details, which could be leveraged for further attacks or data breaches. The lack of known exploits in the wild suggests it is a recently disclosed issue, but the ease of exploitation and high confidentiality impact make it a significant threat. The vulnerability arises from improper handling or filtering of sensitive information before sending data externally, indicating a design or implementation flaw in the Mail Mint software's data transmission logic.

For European organizations using WPFunnels Mail Mint, this vulnerability poses a substantial risk to the confidentiality of sensitive data. Since Mail Mint is an email marketing and automation tool, it likely handles customer data, campaign details, and possibly personal identifiable information (PII). Unauthorized disclosure of such data can lead to GDPR violations, resulting in heavy fines and reputational damage. Additionally, leaked sensitive information could facilitate targeted phishing attacks, social engineering, or unauthorized access to other systems. The vulnerability does not affect integrity or availability directly but compromises trust and privacy, which are critical for compliance and customer confidence in Europe. Organizations relying on Mail Mint for email campaigns or customer communications should consider this vulnerability a priority for remediation to avoid data leakage and regulatory consequences.

Since no official patches are currently available, European organizations should implement immediate compensating controls. These include: 1) Temporarily disabling or limiting the use of Mail Mint for sensitive campaigns until a patch is released. 2) Conducting a thorough audit of data being sent through Mail Mint to identify and remove any embedded sensitive information. 3) Implementing network-level controls such as egress filtering and data loss prevention (DLP) solutions to detect and block unauthorized transmission of sensitive data. 4) Monitoring outbound traffic for unusual or unexpected data patterns that could indicate exploitation attempts. 5) Engaging with WPFunnels support or vendor channels to obtain timelines for patches or updates. 6) Educating staff about the risks and ensuring that sensitive data is not unnecessarily embedded in email templates or automation workflows. Once patches are available, prompt application is critical. Additionally, organizations should review their incident response plans to quickly address any potential data leakage incidents stemming from this vulnerability.
