CVE-2025-41114 is a missing authorization vulnerability classified under CWE-862 affecting CanalDenuncia.app, a platform likely used for whistleblowing or complaint management. The vulnerability arises because the backend API endpoint '/backend/api/buscarDocumentosByIdDenunciaUsuario.php' accepts POST requests with parameters 'id_denuncia' and 'id_user' but does not enforce authorization checks to verify that the requesting user is permitted to access the requested data. This lack of access control allows an attacker to craft POST requests with arbitrary 'id_denuncia' and 'id_user' values to retrieve documents or information belonging to other users without authentication or any user interaction. The vulnerability has a CVSS 4.0 base score of 8.7, indicating high severity due to network attack vector, no required privileges or user interaction, and a high impact on confidentiality. The vulnerability was reserved in April 2025 and published in November 2025, with no known exploits in the wild as of now. The absence of patches or mitigations from the vendor suggests that organizations must implement their own controls. The flaw compromises confidentiality severely, as sensitive whistleblower or complaint data could be exposed, potentially leading to privacy violations, reputational damage, and regulatory penalties. The vulnerability affects version 0 of the product, which may indicate an early or initial release. The technical details confirm the vulnerability is straightforward to exploit remotely without authentication, making it a critical risk for any deployment of CanalDenuncia.app.

For European organizations, the impact of CVE-2025-41114 is significant due to the sensitive nature of data typically handled by whistleblowing platforms like CanalDenuncia.app. Unauthorized access to complaint or denunciation documents can lead to breaches of personal data protected under GDPR, resulting in legal and financial penalties. Confidentiality loss can undermine trust in whistleblowing mechanisms, discouraging legitimate reporting and harming organizational transparency. The exposure of sensitive information could also lead to targeted attacks, blackmail, or reputational damage. Since the vulnerability requires no authentication and can be exploited remotely, it broadens the attack surface considerably. Organizations relying on CanalDenuncia.app for compliance or internal reporting must consider this a critical threat to data privacy and integrity. The lack of known exploits in the wild provides a window for proactive mitigation, but the high CVSS score and ease of exploitation necessitate urgent action. Additionally, regulatory bodies in Europe may scrutinize affected organizations more closely if breaches occur due to this vulnerability.

To mitigate CVE-2025-41114, organizations should immediately implement strict authorization checks on the '/backend/api/buscarDocumentosByIdDenunciaUsuario.php' endpoint to ensure that users can only access documents associated with their own 'id_user' and authorized 'id_denuncia' values. This includes validating session tokens or authentication credentials and enforcing role-based access control (RBAC) or attribute-based access control (ABAC) mechanisms. If vendor patches become available, they should be applied without delay. In the absence of patches, organizations should consider deploying web application firewalls (WAFs) with custom rules to detect and block suspicious POST requests containing unauthorized parameter values. Logging and monitoring of API access should be enhanced to detect anomalous access patterns indicative of exploitation attempts. Additionally, organizations should review and minimize data exposure in API responses and consider encrypting sensitive data at rest and in transit. Conducting security audits and penetration testing focused on authorization logic can help identify similar weaknesses. Finally, user awareness and incident response plans should be updated to address potential data breaches stemming from this vulnerability.
