CVE-2026-45722

Estado: AnalizadaAlta (7.1)—

Nextcloud is an open source content collaboration platform. From versions 0.9.0 to before 0.9.7, and 1.0.0 to before 1.0.2, a missing sanitization in the Tables app allowed a user with access to the tables app to perform a limited SQL injection in the ORDER BY statement of a query. Compared to normal SQL injections, the ORDER BY is limited to extracting a single bit of information per request or to make the database wait for a given time. This issue has been patched in versions 0.9.7 and 1.0.2.

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 ORDER BY requiere acceso autenticado (PR:L) y explotación remota de servicio (T1210). Permite extracción de datos (C:H→T1005), manipulación mínima (I:N, pero T1565.001 por timing attacks) y DoS por delay (A:L→T1499).

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.

Desde las versiones 0.9.0 hasta antes de la 0.9.7, y de la 1.0.0 hasta antes de la 1.0.2, una falta de sanitización en la aplicación Tables permitió a un usuario con acceso a la aplicación Tables realizar una inyección SQL limitada en la declaración ORDER BY de una consulta.
