CVE-2026-1727

Estado: AplazadaCrítica (9.1)—

The Agentspace service was affected by a vulnerability that exposed sensitive information due to the use of predictable Google Cloud Storage bucket names. These names were utilized for error logs and temporary staging during data imports from GCS and Cloud SQL. This predictability allowed an attacker to engage in "bucket squatting" by establishing these buckets before a victim's initial use.

All versions after December 12th, 2025 have been updated to protect from this vulnerability. No user action is required for this.

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.

Vector AV:N sin interacción (UI:N) permite explotación remota de aplicación expuesta (T1190). La 'bucket squatting' sobre nombres predecibles expone datos sensibles en logs y staging (T1005, CWE-200).

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.
