Opera before 11.60 does not properly consider the number of . (dot) characters that conventionally exist in domain names of different top-level domains, which allows remote attackers to bypass the Same Origin Policy by leveraging access to a different domain name in the same top-level domain, as demonstrated by the .no or .uk domain.
CVE-2011-4682 1 Opera 1 Opera Browser 2025-04-11 N/A
The JavaScript engine in Opera before 11.60 does not properly implement the in operator, which allows remote attackers to bypass the Same Origin Policy via vectors related to variables on different web sites.
CVE-2010-2421 1 Opera 1 Opera Browser 2025-04-11 N/A
Multiple unspecified vulnerabilities in Opera before 10.54 have unknown impact and attack vectors related to (1) "extremely severe," (2) "highly severe," (3) "moderately severe," and (4) "less severe" issues.
CVE-2012-4142 4 Apple, Linux, Microsoft and 1 more 4 Mac Os X, Linux Kernel, Windows and 1 more 2025-04-11 N/A
Opera before 12.01 on Windows and UNIX, and before 11.66 and 12.x before 12.01 on Mac OS X, ignores some characters in HTML documents in unspecified circumstances, which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks via a crafted document.

Opera before 10.63 does not prevent interpretation of a cross-origin document as a CSS stylesheet when the document lacks a CSS token sequence, which allows remote attackers to obtain sensitive information via a crafted document.
CVE-2010-4582 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera before 11.00 does not properly handle security policies during updates to extensions, which might allow remote attackers to bypass intended access restrictions via unspecified vectors.
CVE-2010-4583 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera before 11.00, when Opera Turbo is enabled, does not display a page's security indication, which makes it easier for remote attackers to spoof trusted content via a crafted web site.
CVE-2011-0684 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera before 11.01 does not properly handle redirections and unspecified other HTTP responses, which allows remote web servers to obtain sufficient access to local files to use these files as page resources, and consequently obtain potentially sensitive information from the contents of the files, via an unknown response manipulation.
CVE-2011-0687 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera before 11.01 does not properly implement Wireless Application Protocol (WAP) dropdown lists, which allows user-assisted remote attackers to cause a denial of service (application crash) via a crafted WAP document.

Opera before 12.01 on Windows and UNIX, and before 11.66 and 12.x before 12.01 on Mac OS X, does not properly escape characters in DOM elements, which makes it easier for remote attackers to bypass cross-site scripting (XSS) protection mechanisms via a crafted HTML document.
CVE-2011-2614 1 Opera 1 Opera Browser 2025-04-11 N/A
The SVG implementation in Opera before 11.50 allows remote attackers to cause a denial of service (application crash) via vectors involving a path on which many characters are drawn.
CVE-2011-2620 1 Opera 1 Opera Browser 2025-04-11 N/A
Unspecified vulnerability in Opera before 11.50 allows remote attackers to cause a denial of service (application crash) via vectors involving SVG animation.
CVE-2011-2626 1 Opera 1 Opera Browser 2025-04-11 N/A

Opera before 11.11 allows user-assisted remote attackers to cause a denial of service (application crash) via a crafted web page that is not properly handled during a reload occurring after the opening of a popup of the Easy Sticky Note extension.
CVE-2009-3046 1 Opera 1 Opera Browser 2025-04-09 7.5 High
Opera before 10.00 does not check all intermediate X.509 certificates for revocation, which makes it easier for remote SSL servers to bypass validation of the certificate chain via a revoked certificate.
CVE-2007-2809 1 Opera 1 Opera Browser 2025-04-09 N/A
Buffer overflow in the transfer manager in Opera before 9.21 for Windows allows user-assisted remote attackers to execute arbitrary code via a crafted torrent file. NOTE: due to the lack of details, it is not clear if this is the same issue as CVE-2007-2274.
