Opera before 10.63 does not properly select the security context of JavaScript code associated with an error page, which allows user-assisted remote attackers to conduct cross-site scripting (XSS) attacks via a crafted web site.

Security readout for executives and security teams

This is an old Opera browser flaw. Before version 10.63, JavaScript tied to an error page could run in the wrong security context, enabling cross-site scripting if a user visited a crafted website. Exposure is most likely limited to environments still running Opera versions before 10.63, including legacy desktops, kiosks, or archived virtual machines. Modern managed browser fleets are unlikely to be exposed. Treat as a legacy exposure cleanup item. Escalate only if old Opera versions remain in production, kiosk, or high-risk browsing environments. Mitigation focus: Inventory systems for Opera versions before 10.63.; Upgrade affected Opera installations to 10.63 or later.; Remove unsupported legacy Opera browsers where business use is unnecessary..
