Opera 11.60 and earlier does not prevent capture of data about the times of Same Origin Policy violations during IFRAME loading attempts, which makes it easier for remote attackers to determine whether a document exists in the browser cache via crafted JavaScript code.

Security readout for executives and security teams

This is an old Opera browser privacy issue. A website could use timing differences during blocked frame loads to infer whether certain documents were already in a user's browser cache. It is not described as code execution or full data theft, but it could reveal browsing-related information. Exposure is most plausible where Opera 11.60 or earlier remains in use. Modern managed environments are unlikely to be affected unless they retain legacy browsers for compatibility testing or old kiosk-style systems. Low priority for most organizations because this affects an obsolete browser and the source describes cache inference, not system compromise. Treat it as a legacy browser hygiene issue if old Opera remains deployed. Mitigation focus: Inventory endpoints for Opera 11.60 or earlier.; Retire or update affected legacy Opera installations.; Check Opera or advisory guidance for fixed-version details..
