Go to dashboardBeans-component flaw in the Java 7 browser plug-in (JDK/JRE 7 Update 6 and before). A malicious web page running an untrusted applet or Web Start app escapes the sandbox and runs code (CVSS 2.0 10.0). Exploited in the wild since Aug 2012, Metasploit module public, in CISA KEV since 2022-03-03. Oracle says it does not apply to servers, standalone desktop apps or Java SE Embedded. The same alert also fixes CVE-2012-1682 and CVE-2012-3136.

Multiple vulnerabilities in the Java Runtime Environment (JRE) component in Oracle Java SE 7 Update 6 and earlier allow remote attackers to execute arbitrary code via a crafted applet that bypasses SecurityManager restrictions by (1) using com.sun.beans.finder.ClassFinder.findClass and leveraging an exception with the forName method to access restricted classes from arbitrary packages such as sun.awt.SunToolkit, then (2) using "reflection with a trusted immediate caller" to leverage the getField method to access and modify private fields, as exploited in the wild in August 2012 using Gondzz.class and Gondvv.class.
