CVE-2026-5086

Estado: AnalizadaAlta (7.5)—

Crypt::SecretBuffer versions before 0.019 for Perl is suseceptible to timing attacks.

For example, if Crypt::SecretBuffer was used to store and compare plaintext passwords, then discrepencies in timing could be used to guess the secret password.

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
Puntuación base: 7.5

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 0.44%
Percentil entre todas las CVEs puntuadas: 36
Fecha de la puntuación: 6/10/2026
