CVE-2004-1491 4 Gentoo, Kde, Opera and 1 more 4 Linux, Kde, Opera Browser and 1 more 2026-04-16 N/A
Opera 7.54 and earlier uses kfmclient exec to handle unknown MIME types, which allows remote attackers to execute arbitrary code via a shortcut or launcher that contains an Exec entry.
CVE-2003-1420 1 Opera 1 Opera Browser 2026-04-16 N/A
Cross-site scripting (XSS) vulnerability in Opera 6.0 through 7.0 with automatic redirection disabled allows remote attackers to inject arbitrary web script or HTML via the HTTP Location header.
CVE-2004-0717 3 Linux, Microsoft, Opera 3 Linux Kernel, Windows, Opera Browser 2026-04-16 N/A
Opera 7.51 for Windows and 7.50 for Linux does not properly prevent a frame in one domain from injecting content into a frame that belongs to another domain, which facilitates web site spoofing and other attacks, aka the frame injection vulnerability.
CVE-2003-1387 1 Opera 1 Opera Browser 2026-04-16 N/A
Buffer overflow in Opera 6.05 and 6.06, and possibly other versions, allows remote attackers to execute arbitrary code via a URL with a long username.
CVE-2005-3041 1 Opera 1 Opera Browser 2026-04-16 N/A
Unspecified "drag-and-drop vulnerability" in Opera Web Browser before 8.50 on Windows allows "unintentional file uploads."
CVE-2005-3006 1 Opera 1 Opera Browser 2026-04-16 N/A
The mail client in Opera before 8.50 opens attached files from the user's cache directory without warning the user, which might allow remote attackers to inject arbitrary web script and spoof attachment filenames.
CVE-2005-1669 1 Opera 1 Opera Browser 2026-04-16 N/A
Cross-site scripting (XSS) vulnerability in Opera 8.0 Final Build 1095 allows remote attackers to inject arbitrary web script or HTML via "javascript:" URLs when a new window or frame is opened, which allows remote attackers to bypass access restrictions and perform unauthorized actions on other domains.
CVE-2004-0537 1 Opera 1 Opera Browser 2026-04-16 N/A
Opera 7.50 and earlier allows remote web sites to provide a "Shortcut Icon" (favicon) that is wider than expected, which could allow the web sites to spoof a trusted domain and facilitate phishing attacks using a wide icon and extra spaces.
CVE-2004-1157 1 Opera 1 Opera Browser 2026-04-16 N/A
Opera 7.x up to 7.54, and possibly other versions, allows remote attackers to spoof arbitrary web sites by injecting content from one window into a target window whose name is known but resides in a different domain, as demonstrated using a pop-up window on a trusted web site, aka the "window injection" vulnerability.
CVE-2006-3199 1 Opera 1 Opera Browser 2026-04-16 N/A
Opera 9 allows remote attackers to cause a denial of service (crash) via an A tag with an href attribute with a URL containing a long hostname, which triggers an out-of-bounds operation.
CVE-2016-6908 1 Opera 1 Opera Browser 2025-04-20 N/A
Characters from languages are such as Arabic, Hebrew are displayed from RTL (Right To Left) order in Opera 37.0.2192.105088 for Android, due to mishandling of several unicode characters such as U+FE70, U+0622, U+0623 etc and how they are rendered combined with (first strong character) such as an IP address or alphabet could lead to a spoofed URL. It was noticed that by placing neutral characters such as "/", "?" in filepath causes the URL to be flipped and displayed from Right To Left. However, in order for the URL to be spoofed the URL must begin with an IP address followed by neutral characters as omnibox considers IP address to be combination of punctuation and numbers and since LTR (Left To Right) direction is not properly enforced, this causes the entire URL to be treated and rendered from RTL (Right To Left). However, it doesn't have be an IP address, what matters is that first strong character (generally, alphabetic character) in the URL must be an RTL character.
CVE-2016-4075 1 Opera 2 Opera Browser, Opera Mini 2025-04-20 6.1 Medium
Opera Mini 13 and Opera Stable 36 allow remote attackers to spoof the displayed URL via a crafted HTML document, related to the about:blank URL.
CVE-2016-7153 5 Apple, Google, Microsoft and 2 more 6 Safari, Chrome, Edge and 3 more 2025-04-12 N/A
The HTTP/2 protocol does not consider the role of the TCP congestion window in providing information about content length, which makes it easier for remote attackers to obtain cleartext data by leveraging a web-browser configuration in which third-party cookies are sent, aka a "HEIST" attack.
CVE-2015-8960 7 Apple, Google, Ietf and 4 more 18 Safari, Chrome, Transport Layer Security and 15 more 2025-04-12 8.1 High
The TLS protocol 1.2 and earlier supports the rsa_fixed_dh, dss_fixed_dh, rsa_fixed_ecdh, and ecdsa_fixed_ecdh values for ClientCertificateType but does not directly document the ability to compute the master secret in certain situations with a client secret key and server public key but not a server secret key, which makes it easier for man-in-the-middle attackers to spoof TLS servers by leveraging knowledge of the secret key for an arbitrary installed client X.509 certificate, aka the "Key Compromise Impersonation (KCI)" issue.
CVE-2010-2663 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera before 10.60 allows remote attackers to cause a denial of service (application hang) via an ended event handler that changes the SRC attribute of an AUDIO element.
CVE-2010-2662 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera before 10.60 allows remote attackers to bypass the popup blocker via a javascript: URL and a "fake click."
CVE-2010-5068 1 Opera 1 Opera Browser 2025-04-11 N/A
The Cascading Style Sheets (CSS) implementation in Opera 10.5 does not properly handle the :visited pseudo-class, which allows remote attackers to obtain sensitive information about visited web pages via a crafted HTML document, a related issue to CVE-2010-2264.
CVE-2010-2455 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera does not properly manage the address bar between the request to open a URL and the retrieval of the new document's content, which might allow remote attackers to conduct spoofing attacks via a crafted HTML document, a related issue to CVE-2010-1206.
CVE-2014-1870 2 Apple, Opera 2 Mac Os X, Opera Browser 2025-04-11 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-2012-4143 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, 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.
