Opera before 11.00, when Opera Turbo is used, does not properly present information about problematic X.509 certificates on https web sites, which might make it easier for remote attackers to spoof trusted content via a crafted web site.

Security readout for executives and security teams

This is an old Opera browser issue affecting HTTPS trust signals when Opera Turbo is used. A user could be shown misleading or incomplete information about bad certificates, making spoofed trusted-looking content easier to believe. Exposure is likely limited to legacy systems still running Opera versions before 11.00 with Opera Turbo enabled. Modern environments are unlikely to be affected unless old browser builds remain in use. Low immediate urgency for most organizations, but clean up any legacy Opera use. The business risk is mainly phishing or spoofed-content trust failure on outdated endpoints. Mitigation focus: Remove or upgrade Opera versions earlier than 11.00.; Disable Opera Turbo on any legacy Opera installation pending replacement.; Check Opera 11.00 changelogs and vendor guidance for platform-specific fixes..
