Opera before 10.10 permits cross-origin loading of CSS stylesheets even when the stylesheet download has an incorrect MIME type and the stylesheet document is malformed, which allows remote attackers to obtain sensitive information via a crafted document.

Security readout for executives and security teams

This is an old Opera browser issue. Versions before 10.10 could load malformed cross-origin CSS despite incorrect MIME typing, letting a malicious web page potentially read information it should not access. Business risk depends on whether legacy Opera is still present in user, kiosk, or embedded browsing environments. Exposure is most likely in legacy endpoints, bundled browsers, kiosks, or archived systems still using Opera before 10.10. The bundle does not establish exposure for current Opera or other modern browsers under this CVE. Low urgency for modern fleets, higher priority if legacy browsers remain in production. Confirm exposure first; remediate affected installations because the issue crosses same-origin boundaries and may disclose sensitive data. Mitigation focus: Identify any Opera installations older than 10.10.; Upgrade, remove, or isolate affected legacy Opera browsers.; Check OS and vendor advisories for packaged browser updates..
