|---|---|---|---|---|
| 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-2006-3945 | 2 Microsoft, Opera | 2 Windows Xp, Opera Browser | 2026-04-16 | N/A |
| The CSS functionality in Opera 9 on Windows XP SP2 allows remote attackers to cause a denial of service (crash) by setting the background property of a DHTML element to a long http or https URL, which triggers memory corruption. | ||||
| 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-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-2005-3750 | 1 Opera | 1 Opera Browser | 2026-04-16 | N/A |
| Opera before 8.51 on Linux and Unix systems allows remote attackers to execute arbitrary code via shell metacharacters (backticks) in a URL that another product provides in a command line argument when launching Opera. | ||||
| 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-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-2005-0238 | 4 Gnome, Mozilla, Omnigroup and 1 more | 5 Epiphany, Camino, Mozilla and 2 more | 2026-04-16 | N/A |
| The International Domain Name (IDN) support in Epiphany 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-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-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-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-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-2011-0685 | 1 Opera | 1 Opera Browser | 2025-04-11 | N/A |
| The Delete Private Data feature in Opera before 11.01 does not properly implement the "Clear all email account passwords" option, which might allow physically proximate attackers to access an e-mail account via an unattended workstation. | ||||
| 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-2011-0683 | 1 Opera | 1 Opera Browser | 2025-04-11 | N/A |
| Opera before 11.01 does not properly restrict the use of opera: URLs, which makes it easier for remote attackers to conduct clickjacking attacks via a crafted web site. | ||||
| CVE-2011-3389 | 9 Canonical, Debian, Google and 6 more | 21 Ubuntu Linux, Debian Linux, Chrome and 18 more | 2025-04-11 | N/A |
| The SSL protocol, as used in certain configurations in Microsoft Windows and Microsoft Internet Explorer, Mozilla Firefox, Google Chrome, Opera, and other products, encrypts data by using CBC mode with chained initialization vectors, which allows man-in-the-middle attackers to obtain plaintext HTTP headers via a blockwise chosen-boundary attack (BCBA) on an HTTPS session, in conjunction with JavaScript code that uses (1) the HTML5 WebSocket API, (2) the Java URLConnection API, or (3) the Silverlight WebClient API, aka a "BEAST" attack. | ||||
| 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. | ||||
| CVE-2012-4144 | 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, does not properly escape characters in DOM elements, which makes it easier for remote attackers to bypass cross-site scripting (XSS) protection mechanisms via a crafted HTML document. | ||||
