CVE-2009-3831 2 Microsoft, Opera 2 Windows, Opera Browser 2025-04-09 9.3 HIGH N/A
Opera before 10.01 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted domain name.
CVE-2007-3142 1 Opera 1 Opera Browser 2025-04-09 5.8 MEDIUM N/A
Visual truncation vulnerability in Opera 9.21 allows remote attackers to spoof the address bar and possibly conduct phishing attacks via a long hostname, which is truncated after 34 characters, as demonstrated by a phishing attack using HTTP Basic Authentication.
CVE-2008-4198 1 Opera 1 Opera Browser 2025-04-09 5.0 MEDIUM N/A
Opera before 9.52, when rendering an http page that has loaded an https page into a frame, displays a padlock icon and offers a security information dialog reporting a secure connection, which might allow remote attackers to trick a user into performing unsafe actions on the http page.
CVE-2008-4695 1 Opera 1 Opera 2025-04-09 9.3 HIGH N/A
Opera before 9.60 allows remote attackers to obtain sensitive information and have unspecified other impact by predicting the cache pathname of a cached Java applet and then launching this applet from the cache, leading to applet execution within the local-machine context.
CVE-2008-4696 1 Opera 1 Opera 2025-04-09 4.3 MEDIUM N/A
Cross-site scripting (XSS) vulnerability in Opera.dll in Opera before 9.61 allows remote attackers to inject arbitrary web script or HTML via the anchor identifier (aka the "optional fragment"), which is not properly escaped before storage in the History Search database (aka md.dat).

Unspecified vulnerability in Opera before 9.24 allows remote attackers to overwrite functions on pages from other domains and bypass the same-origin policy via unknown vectors.
CVE-2007-0127 1 Opera 1 Opera Browser 2025-04-09 9.3 HIGH N/A
The Javascript SVG support in Opera before 9.10 does not properly validate object types in a createSVGTransformFromMatrix request, which allows remote attackers to execute arbitrary code via JavaScript code that uses an invalid object in this request that causes a controlled pointer to be referenced during the virtual function call.
CVE-2009-0914 1 Opera 1 Opera Browser 2025-04-09 9.3 HIGH N/A
Opera before 9.64 allows remote attackers to execute arbitrary code via a crafted JPEG image that triggers memory corruption.
CVE-2007-1737 1 Opera 1 Opera Browser 2025-04-09 7.5 HIGH N/A
Opera 9.10 does not check URLs embedded in (1) object or (2) iframe HTML tags against the phishing site blacklist, which allows remote attackers to bypass phishing protection.

Opera before 10.01 does not properly restrict HTML in a (1) RSS or (2) Atom feed, which allows remote attackers to conduct cross-site scripting (XSS) attacks, and conduct cross-zone scripting attacks involving the Feed Subscription Page to read feeds or create feed subscriptions, via a crafted feed, related to the rendering of the application/rss+xml content type as "scripted content."
CVE-2008-1081 1 Opera 1 Opera Browser 2025-04-09 6.8 MEDIUM N/A
Opera before 9.26 allows user-assisted remote attackers to execute arbitrary script via images that contain custom comments, which are treated as script when the user displays the image properties.
CVE-2007-3819 1 Opera 1 Opera Browser 2025-04-09 5.0 MEDIUM N/A
Opera 9.21 allows remote attackers to spoof the data: URI scheme in the address bar via a long URI with trailing whitespace, which prevents the beginning of the URI from being displayed.

Opera 9.52 and earlier, and 10.00 Beta 3 Build 1699, does not properly block data: URIs in Location headers in HTTP responses, which allows remote attackers to conduct cross-site scripting (XSS) attacks via vectors related to (1) injecting a Location header that contains JavaScript sequences in a data:text/html URI or (2) entering a data:text/html URI with JavaScript sequences when specifying the content of a Location header. NOTE: the JavaScript executes outside of the context of the HTTP site.
CVE-2006-6955 1 Opera 1 Opera Browser 2025-04-09 4.3 MEDIUM N/A
