CVE-2026-32285

Estado: ModificadaAlta (7.5)—
The Delete function fails to properly validate offsets when processing malformed JSON input. This can lead to a negative slice index and a runtime panic, allowing a denial of service attack.
CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Puntuación base: 7.5
Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 0.97%
Percentil entre todas las CVEs puntuadas: 61
Fecha de la puntuación: 5/10/2026
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).
🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.
ExplotaciónT1190 Exploit Public-Facing Applicationinitial access95 %
Impacto principalT1499.004 Application or System Exploitationimpact90 %
Vector CVSS con AV:N/PR:N/UI:N indica explotación remota sin privilegios (T1190). La vulnerabilidad causa panic en tiempo de ejecución por validación deficiente de offsets, resultando en DoS (T1499.004: Application Exhaustion).
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.
