CVE-2012-3557 1 Opera 1 Opera Browser 2023-12-10 5.0 MEDIUM N/A
Opera before 11.65 does not properly restrict the reading of JSON strings, which allows remote attackers to perform cross-domain loading of JSON resources and consequently obtain sensitive information via a crafted web site.
CVE-2012-3560 1 Opera 1 Opera Browser 2023-12-10 4.3 MEDIUM N/A
Opera before 11.65 does not ensure that the address field corresponds to the displayed web page during blocked navigation, which makes it easier for remote attackers to conduct spoofing attacks by detecting and preventing attempts to load a different web page.
CVE-2010-4580 1 Opera 1 Opera Browser 2023-12-10 5.0 MEDIUM N/A
Opera before 11.00 does not clear WAP WML form fields after manual navigation to a new web site, which allows remote attackers to obtain sensitive information via an input field that has the same name as an input field on a previously visited web site.
CVE-2011-2621 1 Opera 1 Opera Browser 2023-12-10 5.0 MEDIUM N/A
Unspecified vulnerability in Opera before 11.50 allows remote attackers to cause a denial of service (application crash) via vectors related to form layout.
CVE-2010-4584 1 Opera 1 Opera Browser 2023-12-10 2.6 LOW N/A
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.
CVE-2011-2640 1 Opera 1 Opera Browser 2023-12-10 5.0 MEDIUM N/A
