Published: 27 January 2026
Summary
CVE-2026-1478 is a critical-severity SQL Injection (CWE-89) vulnerability in Quatuor Evaluacion De Desempeno. Its CVSS base score is 9.3 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 24.4th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Deeper analysis
CVE-2026-1478 is an out-of-band SQL injection vulnerability (OOB SQLi) affecting the Performance Evaluation (EDD) application developed by Gabinete Técnico de Programación. The flaw resides in the parameters 'Id_usuario' and 'Id_evaluacion' within the '/evaluacion_hca_evalua.aspx' endpoint, enabling attackers to extract sensitive database information through external channels without the application directly returning the data, thereby compromising confidentiality. The vulnerability carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N) and is associated with CWE-89 (SQL Injection). It was published on 2026-01-27.
The vulnerability can be exploited remotely over the network by unauthenticated attackers with low complexity and no user interaction required. Successful exploitation allows extraction of sensitive information from the database via out-of-band techniques, such as DNS or HTTP requests to attacker-controlled servers, leading to high-impact confidentiality breaches without affecting integrity or availability.
The INCIBE advisory at https://www.incibe.es/en/incibe-cert/notices/aviso/out-band-sql-injection-quatuor-performance-evaluation provides details on the issue, though specific mitigation steps or patches are not detailed in available information.
