CVE-2009-2070 1 Opera 1 Opera Browser 2026-04-23 N/A
Opera displays a cached certificate for a (1) 4xx or (2) 5xx CONNECT response page returned by a proxy server, which allows man-in-the-middle attackers to spoof an arbitrary https site by letting a browser obtain a valid certificate from this site during one request, and then sending the browser a crafted 502 response page upon a subsequent request.
CVE-2007-3142 1 Opera 1 Opera Browser 2026-04-23 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-2008-1081 1 Opera 1 Opera Browser 2026-04-23 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-2008-1762 1 Opera 1 Opera Browser 2026-04-23 N/A
Opera before 9.27 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted scaled image pattern in an HTML CANVAS element, which triggers memory corruption.
CVE-2009-2351 1 Opera 1 Opera Browser 2026-04-23 N/A
Opera 9.52 and earlier does not block javascript: URIs in Refresh headers in HTTP responses, which allows remote attackers to conduct cross-site scripting (XSS) attacks via vectors related to (1) injecting a Refresh header or (2) specifying the content of a Refresh header, a related issue to CVE-2009-1312. NOTE: it was later reported that 10.00 Beta 3 Build 1699 is also affected.
CVE-2008-2714 1 Opera 1 Opera Browser 2026-04-23 N/A
Opera before 9.26 allows remote attackers to misrepresent web page addresses using "certain characters" that "cause the page address text to be misplaced."
CVE-2007-6520 1 Opera 1 Opera Browser 2026-04-23 N/A
Opera before 9.25 allows remote attackers to conduct cross-domain scripting attacks via unknown vectors related to plug-ins.
CVE-2009-1234 1 Opera 1 Opera Browser 2026-04-23 N/A
Opera 9.64 allows remote attackers to cause a denial of service (application crash) via an XML document containing a long series of start-tags with no corresponding end-tags. NOTE: it was later reported that 9.52 is also affected.
CVE-2008-7245 1 Opera 1 Opera Browser 2026-04-23 N/A

The canvas.createPattern function in Opera 9.x before 9.22 for Linux, FreeBSD, and Solaris does not clear memory before using it to process a new pattern, which allows remote attackers to obtain sensitive information (memory contents) via JavaScript.

Opera before 9.52 on Windows, Linux, FreeBSD, and Solaris, when processing custom shortcut and menu commands, can produce argument strings that contain uninitialized memory, which might allow user-assisted remote attackers to execute arbitrary code or conduct other attacks via vectors related to activation of a shortcut.
CVE-2007-0802 2 Mozilla, Opera 2 Firefox, Opera Browser 2026-04-23 N/A
Mozilla Firefox 2.0.0.1 allows remote attackers to bypass the Phishing Protection mechanism by adding certain characters to the end of the domain name, as demonstrated by the "." and "/" characters, which is not caught by the Phishing List blacklist filter.

Opera before 10.01 on Windows does not prevent use of Web fonts in rendering the product's own user interface, which allows remote attackers to spoof the address field via a crafted web site.
CVE-2006-4819 1 Opera 1 Opera Browser 2026-04-23 N/A
Heap-based buffer overflow in Opera 9.0 and 9.01 allows remote attackers to execute arbitrary code via a long URL in a tag (long link address).

The Fast Forward feature in Opera before 9.61, when a page is located in a frame, executes a javascript: URL in the context of the outermost page instead of the page that contains this URL, which allows remote attackers to conduct cross-site scripting (XSS) attacks.
CVE-2009-3045 1 Opera 1 Opera Browser 2026-04-23 N/A
Opera before 10.00 trusts root X.509 certificates signed with the MD2 algorithm, which makes it easier for man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted server certificate.
