Opera before 11.65 does not ensure that the address field corresponds to the displayed web page during unusually timed changes to this field, which makes it easier for user-assisted remote attackers to conduct spoofing attacks via vectors involving navigation, reloads, and redirects.

Security readout for executives and security teams

This CVE is an address-bar spoofing flaw in Opera before 11.65. A malicious site could make the browser show a web page that does not match the address field during carefully timed navigation, reload, or redirect behavior. The main business risk is phishing or user deception, not direct system takeover. Exposure is most likely limited to legacy systems still running Opera versions earlier than 11.65. Modern managed endpoints are unlikely to be affected unless old browsers remain installed for compatibility or kiosk use. Treat this as a targeted legacy-browser cleanup issue. It is not evidenced as actively exploited, but outdated browsers can materially increase phishing risk and should not remain in production environments. Mitigation focus: Identify and remove Opera versions earlier than 11.65.; Upgrade affected installations to a supported Opera release.; Check Opera changelogs and support guidance for vendor-confirmed remediation details..
