Sensitive Data Exposure in GetPaid Payment Processing

CVE-2026-49064 represents a critical data handling flaw in Stiofan GetPaid versions through 2.8.49, where sensitive information is inadvertently embedded and transmitted in outbound data communications. This Insertion of Sensitive Information vulnerability (CWE-201) exposes payment processors, e-commerce platforms, and financial service providers who rely on GetPaid to credential theft, compliance violations, and customer data breaches. Organizations running affected versions risk exposing authentication tokens, API keys, customer payment details, or other security-critical data to unintended recipients or network observers, potentially leading to unauthorized access and downstream compromise.

While this CVE currently lacks mapped MITRE ATT&CK techniques, Casky.ai's Claude-powered analysis engine would detect the underlying attack patterns through behavioral detection and data flow analysis. Practitioners using Casky would observe findings related to T1041 (Exfiltration Over C2 Channel) and T1020 (Automated Exfiltration) as the vulnerability mechanism—unintended transmission of sensitive data—mirrors attacker exfiltration tactics. Extended reasoning capabilities would flag anomalous data inclusion in API responses, logging outputs, or HTTP headers where secrets should never appear. Security teams would see high-confidence alerts identifying systematic sensitive data leakage patterns across GetPaid transaction logs and network traffic, enabling rapid patch prioritization and data exposure assessment before active exploitation occurs.
