|---|---|---|---|---|
| CVE-2005-2406 | 1 Opera | 1 Opera Browser | 2026-04-16 | N/A |
| Opera 8.01 allows remote attackers to conduct cross-site scripting (XSS) attacks or modify which files are uploaded by tricking a user into dragging an image that is a "javascript:" URI. | ||||
| CVE-2005-2273 | 1 Opera | 1 Opera Browser | 2026-04-16 | N/A |
| Opera 7.x and 8 before 8.01 does not clearly associate a Javascript dialog box with the web page that generated it, which allows remote attackers to spoof a dialog box from a trusted site and facilitates phishing attacks, aka the "Dialog Origin Spoofing Vulnerability." | ||||
| 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-2005-0233 | 5 Mozilla, Omnigroup, Opera and 2 more | 7 Camino, Firefox, Mozilla and 4 more | 2026-04-16 | N/A |
| The International Domain Name (IDN) support in Firefox 1.0, Camino .8.5, and Mozilla before 1.7.6 allows remote attackers to spoof domain names using punycode encoded domain names that are decoded in URLs and SSL certificates in a way that uses homograph characters from other character sets, which facilitates phishing attacks. | ||||
| CVE-2005-1475 | 1 Opera | 1 Opera Browser | 2026-04-16 | N/A |
| The XMLHttpRequest object in Opera 8.0 Final Build 1095 allows remote attackers to bypass access restrictions and perform unauthorized actions on other domains via a redirect. | ||||
| CVE-2004-0473 | 1 Opera | 1 Opera Browser | 2026-04-16 | N/A |
| Argument injection vulnerability in Opera before 7.50 does not properly filter "-" characters that begin a hostname in a telnet URI, which allows remote attackers to insert options to the resulting command line and overwrite arbitrary files via (1) the "-f" option on Windows XP or (2) the "-n" option on Linux. | ||||
| CVE-2004-2570 | 1 Opera | 1 Opera Browser | 2026-04-16 | N/A |
| Opera before 7.54 allows remote attackers to modify properties and methods of the location object and execute Javascript to read arbitrary files from the client's local filesystem or display a false URL to the user. | ||||
| CVE-2006-3198 | 1 Opera | 1 Opera Browser | 2026-04-16 | N/A |
| Integer overflow in Opera 8.54 and earlier allows remote attackers to execute arbitrary code via a JPEG image with large height and width values, which causes less memory to be allocated than intended. | ||||
| CVE-2006-1834 | 1 Opera | 1 Opera Browser | 2026-04-16 | N/A |
| Integer signedness error in Opera before 8.54 allows remote attackers to execute arbitrary code via long values in a stylesheet attribute, which pass a length check. NOTE: a sign extension problem makes the attack easier with shorter strings. | ||||
| 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-2016-6908 | 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-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-2015-4000 | 13 Apple, Canonical, Debian and 10 more | 31 Iphone Os, Mac Os X, Safari and 28 more | 2025-04-12 | N/A |
| The TLS protocol 1.2 and earlier, when a DHE_EXPORT ciphersuite is enabled on a server but not on a client, does not properly convey a DHE_EXPORT choice, which allows man-in-the-middle attackers to conduct cipher-downgrade attacks by rewriting a ClientHello with DHE replaced by DHE_EXPORT and then rewriting a ServerHello with DHE_EXPORT replaced by DHE, aka the "Logjam" issue. | ||||
| 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-2011-0450 | 2 Microsoft, Opera | 2 Windows, Opera Browser | 2025-04-11 | N/A |
| The downloads manager in Opera before 11.01 on Windows does not properly determine the pathname of the filesystem-viewing application, which allows user-assisted remote attackers to execute arbitrary code via a crafted web site that hosts an executable file. | ||||
| CVE-2010-4050 | 1 Opera | 1 Opera Browser | 2025-04-11 | N/A |
| Opera before 10.63 allows remote attackers to cause a denial of service (memory corruption) by referencing an SVG document in an IMG element. | ||||
| CVE-2010-2657 | 3 Apple, Microsoft, Opera | 3 Macos, Windows, Opera Browser | 2025-04-11 | 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-2010-4048 | 1 Opera | 1 Opera Browser | 2025-04-11 | N/A |
| Opera before 10.63 allows user-assisted remote web servers to cause a denial of service (application crash) by sending a redirect during the saving of a file. | ||||
| CVE-2010-4047 | 1 Opera | 1 Opera Browser | 2025-04-11 | N/A |
| Opera before 10.63 does not properly select the security context of JavaScript code associated with an error page, which allows user-assisted remote attackers to conduct cross-site scripting (XSS) attacks via a crafted web site. | ||||
| CVE-2010-2121 | 1 Opera | 1 Opera Browser | 2025-04-11 | N/A |
| Opera 9.52 allows remote attackers to cause a denial of service (resource consumption) via JavaScript code containing an infinite loop that creates IFRAME elements for invalid (1) news:// or (2) nntp:// URIs. | ||||
