CVE-2026-1481 — Out-of-band SQL injection in Quatuor Performance Evaluation

An out-of-band SQL injection vulnerability (OOB SQLi) has been detected in the Performance Evaluation (EDD) application developed by Gabinete Técnico de Programación. Exploiting this vulnerability in the parameter 'Id_usuario' in '/evaluacion_objetivos_anyo_sig_ver_auto.aspx', could allow an attacker to extract sensitive information from the database through external channels, without the affected application returning the data directly, compromising the confidentiality of the stored information.

Low

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.

How the score was calculated

EPSS 0.4% (30-day exploitation probability)+4
Technical severity (high)+6
Automatable exploitation (SSVC)+3

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Exploitation

Not confirmed

Not in CISA KEV — an absence of record, not proof it is unexploited.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

Identify exposed assets running the affected vendor/product/version combinations (Quatuor Evaluacion De Desempeno, Quatuor Evaluación de Desempeño (EDD)).
The attack is network-based and needs no privileges: restrict exposure (ACLs, VPN, WAF) until patched.
No fix documented in the sources: reduce exposure and monitor the vendor advisory.
Search available logs for exploit probes matching the vulnerability class (injection), errors and authentication anomalies.

Detection

Read off the CVSS vector and the weakness class. Starting points, not tested rules.

Prioritize edge telemetry for the network-reachable component (proxy, WAF, IDS/IPS).
Look for parameters with command/query metacharacters and unexpected child processes of the service.

What should defenders know first?

CVE-2026-1481 is "Out-of-band SQL injection in Quatuor Performance Evaluation", rated High. It affects Evaluacion De Desempeno (Quatuor); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 7.5 describes technical severity. EPSS 0.37% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
