Security readout for executives and security teams
Plain-English summary
CVE-2026-1480 is a critical SQL injection issue in Quatuor Evaluación de Desempeño (EDD). An unauthenticated network attacker could use the affected user identifier parameter to pull sensitive database information through external channels. Sources do not state that it is being actively exploited.
Executive priority
Treat as urgent for any Quatuor EDD deployment, especially if internet-facing. The issue may allow sensitive HR or performance data exposure without authentication. Immediate inventory, access restriction, monitoring, and vendor-guidance review are warranted.
Technical view
INCIBE reports out-of-band SQL injection in /evaluacion_objetivos_anyo_sig_evalua.aspx via the Id_usuario parameter. The CVSS 4.0 score is 9.3, with network access, low complexity, no privileges, and no user interaction required. Impact is primarily confidentiality, with high integrity impact and low availability impact.
Likely exposure
Organizations running Quatuor Performance Evaluation / Evaluación de Desempeño (EDD) are potentially exposed. The CVE record lists all versions as affected. Internet-facing deployments are higher risk because the vulnerability is network-reachable and requires no authentication.
Exploitation context
The public sources describe the vulnerability class and affected endpoint, but do not provide evidence of active exploitation. It is not listed as CISA KEV in the provided data. Out-of-band SQL injection can enable data extraction even when the application does not display database results directly.
Researcher notes
Evidence is limited to the CVE record and INCIBE notice. No patch details, exploit publication, or active exploitation evidence are included in the provided sources. Avoid assuming affected configurations beyond Quatuor EDD and the stated endpoint and parameter.
Mitigation direction
- Check INCIBE and vendor advisories for official remediation guidance or updates.
- Identify all Quatuor EDD instances and prioritize internet-facing systems.
- Restrict external access to the EDD application where business operations allow.
- Apply vendor-provided fixes or configuration changes when available.
- Increase monitoring for unusual outbound database or application server connections.
Validation and detection
- Confirm whether Quatuor EDD is deployed in the environment.
- Determine whether /evaluacion_objetivos_anyo_sig_evalua.aspx is reachable from untrusted networks.
- Review vendor version information against the advisory’s affected scope.
- Use authorized vulnerability testing to verify exposure without extracting data.
- Review logs for suspicious requests involving Id_usuario and unusual outbound callbacks.

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
