CVE-2026-5086

Status: AnalyzedHigh (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

Version: 3.1
Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
Base score: 7.5

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 0.44%
Percentile among all scored CVEs: 36
Score date: 10/5/2026

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
