The Java Runtime Environment (JRE) component in Oracle Java SE 7 Update 17 and earlier, 6 Update 43 and earlier, 5.0 Update 41 and earlier, and JavaFX 2.2.7 and earlier allows remote attackers to execute arbitrary code via vectors related to 2D, as demonstrated by Joshua Drake during a Pwn2Own competition at CanSecWest 2013.

CVSS

Base score: 10
Version: 2.0
Vector: AV:N/AC:L/Au:N/C:C/I:C/A:C

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 16 %
Percentile among all scored CVEs: 97
Score date: 10/21/2026

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.
