CVE-2026-90559

Estado: Pendiente de análisisAlta (8.7)—

snappy-java through 1.1.10.8 contains an out-of-bounds write vulnerability in Snappy.uncompress(ByteBuffer, ByteBuffer) because destination buffer capacity is never validated against decompressed size. Attackers can supply valid compressed data that decompresses larger than the destination buffer, causing writes past buffer boundaries and JVM termination.

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.

Vulnerabilidad remota en biblioteca de descompresión (AV:N, PR:N, UI:N) permitiendo DoS al causar escritura fuera de límites y terminación de JVM; CWE-787 (buffer overflow).

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.
