CVE-2026-24539 identifies a missing authorization vulnerability in the ABCdatos Protección de datos – RGPD plugin, a tool designed to assist with GDPR compliance. The vulnerability arises from incorrectly configured access control mechanisms that fail to properly verify whether a user is authorized to access certain data or functionality. This flaw allows remote attackers to bypass authorization checks without requiring authentication or user interaction, enabling them to access data that should be restricted. The affected versions include all releases up to and including version 0.68. The vulnerability impacts confidentiality by potentially exposing sensitive personal data managed by the plugin, but does not affect data integrity or system availability. The CVSS 3.1 base score of 5.3 reflects a network attack vector with low attack complexity, no privileges required, and no user interaction needed. No public exploits or active exploitation have been reported to date. The plugin is used primarily by organizations managing GDPR data protection requirements, making it a relevant concern for entities handling European personal data. The lack of patch links suggests that a fix may not yet be publicly available, emphasizing the need for interim mitigations. This vulnerability highlights the critical importance of robust access control in data protection tools, especially those handling regulated personal information.

For European organizations, this vulnerability poses a risk of unauthorized disclosure of personal data protected under GDPR, potentially leading to regulatory non-compliance, reputational damage, and legal penalties. Although the vulnerability does not allow modification or deletion of data, the exposure of sensitive information can undermine trust and violate data protection principles. Organizations relying on the ABCdatos Protección de datos – RGPD plugin for GDPR compliance may find their data protection measures compromised. The ease of exploitation without authentication increases the threat level, especially for publicly accessible systems. While no active exploitation is known, attackers could leverage this vulnerability to gather intelligence or conduct further attacks. The impact is particularly significant for sectors with high volumes of personal data, such as healthcare, finance, and public administration. Failure to address this vulnerability could also attract scrutiny from European data protection authorities, resulting in fines or mandatory remediation orders.

Organizations should monitor ABCdatos communications for official patches and apply them promptly once available. Until patches are released, restrict network access to the plugin’s administrative and data interfaces using firewalls or VPNs to limit exposure. Implement additional access control layers at the web server or application level to enforce authorization checks. Conduct thorough audits of user permissions and plugin configurations to identify and close potential access gaps. Employ web application firewalls (WAFs) with custom rules to detect and block unauthorized access attempts targeting the plugin. Regularly review logs for suspicious activity related to the plugin’s endpoints. Educate administrators on the risks of misconfigured access controls and the importance of timely updates. Consider alternative GDPR compliance tools with stronger security track records if immediate patching is not feasible. Finally, ensure that incident response plans include procedures for handling potential data exposure incidents stemming from this vulnerability.
