CVE-2009-2476

Status: ModifiedHigh (10)—
The Java Management Extensions (JMX) implementation in Sun Java SE 6 before Update 15, and OpenJDK, does not properly enforce OpenType checks, which allows context-dependent attackers to bypass intended access restrictions by leveraging finalizer resurrection to obtain a reference to a privileged object.
CVSS

Version: 2.0
Vector: AV:N/AC:L/Au:N/C:C/I:C/A:C
Base score: 10
Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 2.88%
Percentile among all scored CVEs: 86
Score date: 10/6/2026
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).
