CVE-2021-22557
Estado: ModificadaAlta (7.8)—💥 Exploit
SLO generator allows for loading of YAML files that if crafted in a specific format can allow for code execution within the context of the SLO Generator. We recommend upgrading SLO Generator past https://github.com/google/slo-generator/pull/173
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
- Puntuación base: 7.8
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 1.58%
- Percentil entre todas las CVEs puntuadas: 75
- Fecha de la puntuación: 7/10/2026
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).
💥 Exploits públicos
Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.
