CVE-2011-2634: Opera before 11.10 allows remote attackers to hijack (1) searches and (2) customizations via unspecified th...

Security readout for executives and security teams

This is an old Opera browser issue. Versions before 11.10 could let remote attackers hijack browser searches or customizations through unspecified third-party applications. The public record does not show code execution, data theft, or active exploitation, so urgency depends mainly on whether obsolete Opera versions remain in use. Likely exposure is limited to endpoints still running Opera older than 11.10, especially unmanaged legacy desktops or archived images. Modern managed fleets are unlikely to be exposed, but this should be verified through software inventory rather than assumed. Treat as a legacy hygiene item unless old Opera installations are still present. If found, remediate promptly because browser search and customization hijacking can enable fraud, user misdirection, and loss of browser trust. Mitigation focus: Inventory endpoints for Opera versions older than 11.10.; Upgrade affected Opera installations to 11.10 or later where supported.; Remove obsolete Opera installations where business use is not required..
