CVE-2006-2426

Status: ModifiedMedium (6.4)—💥 Exploit

Sun Java Runtime Environment (JRE) 1.5.0_6 and earlier, JDK 1.5.0_6 and earlier, and SDK 1.5.0_6 and earlier allows remote attackers to cause a denial of service (disk consumption) by using the Font.createFont function to create temporary files of arbitrary size in the %temp% directory.

CVSS

Version: 2.0
Vector: AV:N/AC:L/Au:N/C:N/I:P/A:P
Base score: 6.4

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 13%
Percentile among all scored CVEs: 96
Score date: 10/13/2026

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).

💥 Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.
