CVE-2026-93292

Estado: Pendiente de análisisAlta (8.4)—

SigNoz versions from 0.88.0 before 0.142.1 contain a SQL injection vulnerability in trace-funnel analytics endpoints that interpolate service_name and span_name fields into ClickHouse string literals without escaping. Authenticated attackers can inject SQL through funnel step definitions to execute arbitrary queries and read results in HTTP responses.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

SQL injection en endpoints autenticados de SigNoz permite lecturas de datos arbitrarias (CWE-89) en ClickHouse; requiere autenticación previa (PR:L) pero afecta disponibilidad e integridad (VC:H/VI:L).

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
