|---|---|---|---|---|
| CVE-2006-3331 | 1 Opera | 1 Opera Browser | 2026-04-16 | N/A |
| Opera before 9.0 does not reset the SSL security bar after displaying a download dialog from an SSL-enabled website, which allows remote attackers to spoof a trusted SSL certificate from an untrusted website and facilitates phishing attacks. | ||||
| CVE-2005-0457 | 1 Opera | 1 Opera Browser | 2026-04-16 | N/A |
| Opera 7.54 and earlier on Gentoo Linux uses an insecure path for plugins, which could allow local users to gain privileges by inserting malicious libraries into the PORTAGE_TMPDIR (portage) temporary directory. | ||||
| CVE-2004-1201 | 1 Opera | 1 Opera Browser | 2026-04-16 | N/A |
| Opera 7.54 allows remote attackers to cause a denial of service (application crash from memory exhaustion), as demonstrated using Javascript code that continuously creates nested arrays and then sorts the newly created arrays. | ||||
| 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-2005-0235 | 1 Opera | 1 Opera Browser | 2026-04-16 | N/A |
| The International Domain Name (IDN) support in Opera 7.54 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-2004-1810 | 1 Opera | 1 Opera Browser | 2026-04-16 | N/A |
| The Javascript engine in Opera 7.23 allows remote attackers to cause a denial of service (crash) by creating a new Array object with a large size value, then writing into that array. | ||||
| CVE-2003-0870 | 1 Opera | 1 Opera Browser | 2026-04-16 | N/A |
| Heap-based buffer overflow in Opera 7.11 and 7.20 allows remote attackers to execute arbitrary code via an HREF with a large number of escaped characters in the server name. | ||||
| CVE-2004-2083 | 1 Opera | 1 Opera Browser | 2026-04-16 | N/A |
| Opera Web Browser 7.0 through 7.23 allows remote attackers to trick users into executing a malicious file by embedding a CLSID in the file name, which causes the malicious file to appear as a trusted file type, aka "File Download Extension Spoofing." | ||||
| 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-2005-1475 | 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-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-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-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-2011-2623 | 1 Opera | 1 Opera Browser | 2025-04-11 | N/A |
| Unspecified vulnerability in the SVG BiDi implementation in Opera before 11.50 allows remote attackers to cause a denial of service (application crash or hang) via unknown vectors. | ||||
| CVE-2011-2620 | 1 Opera | 1 Opera Browser | 2025-04-11 | N/A |
| Unspecified vulnerability in Opera before 11.50 allows remote attackers to cause a denial of service (application crash) via vectors involving SVG animation. | ||||
| CVE-2011-2616 | 1 Opera | 1 Opera Browser | 2025-04-11 | N/A |
| Unspecified vulnerability in Opera before 11.50 allows remote attackers to cause a denial of service (memory consumption) via unknown content on a web page, as demonstrated by test262.ecmascript.org. | ||||
| CVE-2011-2615 | 1 Opera | 1 Opera Browser | 2025-04-11 | N/A |
| Unspecified vulnerability in Opera before 11.50 allows remote attackers to cause a denial of service (application hang) via unknown content on a web page, as demonstrated by domiteca.com. | ||||
| CVE-2012-3560 | 1 Opera | 1 Opera Browser | 2025-04-11 | N/A |
| Opera before 11.65 does not ensure that the address field corresponds to the displayed web page during blocked navigation, which makes it easier for remote attackers to conduct spoofing attacks by detecting and preventing attempts to load a different web page. | ||||
