CVE-2012-6463 1 Opera 1 Opera Browser 2025-04-11 4.3 MEDIUM N/A
Cross-site scripting (XSS) vulnerability in Opera before 12.10 allows remote attackers to inject arbitrary web script or HTML via vectors involving an unspecified sequence of loading of documents and loading of data: URLs.
CVE-2012-3558 1 Opera 1 Opera Browser 2025-04-11 2.6 LOW N/A
Opera before 11.65 does not ensure that the address field corresponds to the displayed web page during unusually timed changes to this field, which makes it easier for user-assisted remote attackers to conduct spoofing attacks via vectors involving navigation, reloads, and redirects.
CVE-2012-1927 1 Opera 1 Opera Browser 2025-04-11 6.4 MEDIUM N/A
Opera before 11.62 allows remote attackers to spoof the address field by triggering the launch of a dialog window associated with a different domain.
CVE-2013-1489 5 Google, Microsoft, Mozilla and 2 more 6 Chrome, Internet Explorer, Firefox and 3 more 2025-04-11 10.0 HIGH N/A
Unspecified vulnerability in the Java Runtime Environment (JRE) component in Oracle Java SE 7 Update 10 and Update 11, when running on Windows using Internet Explorer, Firefox, Opera, and Google Chrome, allows remote attackers to bypass the "Very High" security level of the Java Control Panel and execute unsigned Java code without prompting the user via unknown vectors, aka "Issue 53" and the "Java Security Slider" vulnerability.
CVE-2014-1870 2 Apple, Opera 2 Mac Os X, Opera Browser 2025-04-11 4.3 MEDIUM N/A
Opera before 19 on Mac OS X allows user-assisted remote attackers to spoof the address bar via vectors involving a drag-and-drop operation.
CVE-2010-4583 1 Opera 1 Opera Browser 2025-04-11 2.6 LOW 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-2011-2624 1 Opera 1 Opera Browser 2025-04-11 4.3 MEDIUM N/A
Opera before 11.50 allows user-assisted remote attackers to cause a denial of service (application hang) via a large table, which is not properly handled during a print preview.
CVE-2011-2639 1 Opera 1 Opera Browser 2025-04-11 5.0 MEDIUM N/A
Opera before 11.10 does not properly handle hidden animated GIF images, which allows remote attackers to cause a denial of service (CPU consumption) via an image file that triggers continual repaints.
CVE-2011-1824 1 Opera 1 Opera Browser 2025-04-11 4.3 MEDIUM N/A
The VEGAOpBitmap::AddLine function in Opera before 10.61 does not properly initialize memory during processing of the SIZE attribute of a SELECT element, which allows remote attackers to trigger an invalid memory write operation, and consequently cause a denial of service (application crash) or possibly execute arbitrary code, via a large integer attribute value.
CVE-2011-2629 1 Opera 1 Opera Browser 2025-04-11 5.0 MEDIUM N/A
Unspecified vulnerability in Opera before 11.11 allows remote attackers to cause a denial of service (application crash) via unknown content on a web page, as demonstrated by www.falk.de.
CVE-2013-3211 1 Opera 1 Opera Browser 2025-04-11 10.0 HIGH N/A
Unspecified vulnerability in Opera before 12.15 has unknown impact and attack vectors, related to a "moderately severe issue."
CVE-2012-1930 2 Opera, Unix 2 Opera Browser, Unix 2025-04-11 4.6 MEDIUM N/A
Opera before 11.62 on UNIX uses world-readable permissions for temporary files during printing, which allows local users to obtain sensitive information by reading these files.
CVE-2012-3557 1 Opera 1 Opera Browser 2025-04-11 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-2011-2619 1 Opera 1 Opera Browser 2025-04-11 5.0 MEDIUM N/A
Opera before 11.50 allows remote attackers to cause a denial of service (application crash) via a gradient with many stops, related to the implementation of CANVAS elements, SVG, and Cascading Style Sheets (CSS).

Opera before 10.54 on Windows and Mac OS X does not properly enforce permission requirements for widget filesystem access and directory selection, which allows user-assisted remote attackers to create or modify arbitrary files, and consequently execute arbitrary code, via widget File I/O operations.
CVE-2010-2421 1 Opera 1 Opera Browser 2025-04-11 10.0 HIGH 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-2010-2657 3 Apple, Microsoft, Opera 3 Macos, Windows, Opera Browser 2025-04-11 9.3 HIGH N/A
Opera before 10.60 on Windows and Mac OS X does not properly prevent certain double-click operations from running a program located on a web site, which allows user-assisted remote attackers to execute arbitrary code via a crafted web page that bypasses a dialog.
CVE-2012-4010 1 Opera 1 Opera Browser 2025-04-11 5.0 MEDIUM N/A
Opera before 11.60 allows remote attackers to spoof the address bar via unspecified homograph characters, a different vulnerability than CVE-2010-2660.
CVE-2011-2631 1 Opera 1 Opera Browser 2025-04-11 5.0 MEDIUM N/A
The Cascading Style Sheets (CSS) implementation in Opera before 11.11 does not properly handle the column-count property, which allows remote attackers to cause a denial of service (infinite repaint loop and application hang) via a web page, as demonstrated by an unspecified Wikipedia page.
CVE-2012-4143 4 Apple, Linux, Microsoft and 1 more 4 Mac Os X, Linux Kernel, Windows and 1 more 2025-04-11 6.8 MEDIUM N/A
Opera before 12.01 on Windows and UNIX, and before 11.66 and 12.x before 12.01 on Mac OS X, allows user-assisted remote attackers to trick users into downloading and executing arbitrary files via a small window for the download dialog, a different vulnerability than CVE-2012-1924.
