CVE-2011-0684: Opera before 11.01 does not properly handle redirections and unspecified other HTTP responses, which allows...

Security readout for executives and security teams

Older Opera browsers before 11.01 could be tricked by a malicious web server into treating local files as page resources, potentially exposing sensitive file contents. The public record does not provide CVSS, CWE, or confirmed exploitation evidence. Exposure is most likely on legacy endpoints still running Opera before 11.01 across platforms referenced by Opera’s Windows, Unix, and Mac 11.01 changelogs. Modern environments are unlikely to be exposed unless they retain unsupported historical browser versions. Treat this as a legacy-browser cleanup issue with confidentiality impact. Prioritize removal from managed environments, especially where users handle sensitive files or access untrusted web content. Mitigation focus: Inventory endpoints for Opera versions earlier than 11.01.; Upgrade or retire Opera installations older than 11.01.; Review Opera 11.01 changelogs and support guidance..
