The vulnerability allowed unauthorized access to sensitive financial data including IBANs and tax information, highlighting critical gaps in access controls and encryption. This incident demonstrates how system migrations can introduce security vulnerabilities if proper controls aren't maintained throughout the process. The €240,000 GDPR fine underscores the regulatory consequences of failing to protect personal data integrity and confidentiality.","**Immediate actions:**\n- Implement strong authentication and authorization controls for all APIs\n- Encrypt sensitive data both in transit and at rest during system migrations\n- Conduct security assessments before, during, and after system migrations\n\n**Long-term improvements:**\n- Establish API security governance with regular vulnerability assessments\n- Implement data classification policies to ensure appropriate protection levels\n- Create secure migration procedures with mandatory security checkpoints\n\n**Monitoring measures:**\n- Deploy API monitoring tools to detect unauthorized access attempts\n- Implement data loss prevention (DLP) solutions to monitor sensitive data movement",[12,13,14,15,16,17,18],"CIS Control 3 (Data Protection)","CIS Control 6 (Access Control Management)","NIST AC-2 (Account Management)","NIST AC-3 (Access Enforcement)","NIST SC-8 (Transmission Confidentiality)","GDPR Article 5(1)(f)","GDPR Article 32 (Security of Processing)","published","2026-04-17T14:09:37.766849+00:00","2026-04-17T14:09:37.638+00:00",{"id":7,"url":23,"slug":24,"title":25},"https:\u002F\u002Fgdprhub.eu\u002Findex.php?title=AEPD_(Spain)_-_EXP202406208&diff=51366&oldid=0","aepd-spain-exp202406208-cbb50c","AEPD (Spain) - EXP202406208",[27,33],{"id":28,"name":29,"slug":30,"description":31,"color":32},"1ec88fde-2d0f-4ed8-932a-33f5ccc0fdc7","Access Control","access-control","Excessive privileges, missing MFA, weak auth","#f97316",{"id":34,"name":35,"slug":36,"description":37,"color":38},"c8b843a5-d5a7-41d1-8d3b-cabded09d2ef","Data Protection","data-protection","Unencrypted data, missing DLP, poor classification","#3b82f6",[]]
