Security readout for executives and security teams
CVE-2011-4682 is an old Opera browser flaw affecting versions before 11.60. A malicious website could bypass browser same-origin protections, potentially exposing data across sites in that browser session. Business risk is mainly from unmanaged legacy Opera installations. Exposure is most likely on legacy desktops, kiosks, lab systems, or embedded environments still running Opera before 11.60. Current managed browsers are unlikely to be affected unless old Opera builds remain installed. Treat this as a legacy-browser hygiene issue unless old Opera is present. If affected builds exist, prioritize removal or upgrade because browser same-origin bypasses can expose web-session data. Mitigation focus: Inventory systems for Opera versions older than 11.60.; Upgrade affected Opera installations to 11.60 or later where still supported.; Remove legacy Opera where it is no longer business-required..
