CVE-2007-4381

Status: ModifiedHigh (9.3)—💥 Exploit
Unspecified vulnerability in the font parsing implementation in Sun JDK and JRE 5.0 Update 9 and earlier, and SDK and JRE 1.4.2_14 and earlier, allows remote attackers to perform unauthorized actions via an applet that grants certain privileges to itself.
CVSS

Version: 2.0
Vector: AV:N/AC:M/Au:N/C:C/I:C/A:C
Base score: 9.3
Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 5.42%
Percentile among all scored CVEs: 93
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.
