CVE-2026-9698

Estado: ModificadaCrítica (9.8)—

DBI versions before 1.648 for Perl saved errors in a limited-sized buffer.

Error messages that were returned when RaiseError, PrintError or HandleError were set were written to a 200-byte buffer without a length limit.

Attackers that can influence the error text in an application can trigger a buffer overflow.

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Puntuación base: 9.8

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 0.82%
Percentil entre todas las CVEs puntuadas: 56
Fecha de la puntuación: 6/10/2026

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).
