CVE-2011-2486: Nspluginwrapper

Medium severity, CVSS 5.0. EPSS: 2.5% chance of exploitation in the next 30 days.

nspluginwrapper before 1.4.4 does not properly provide access to NPNVprivateModeBool variable settings, which could prevent Firefox plugins from determining if they should run in Private Browsing mode and allow remote attackers to bypass intended access restrictions, as demonstrated using Flash.
