| 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-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-2005-2407 | 1 Opera | 1 Opera Browser | 2026-04-16 | N/A |
| A design error in Opera 8.01 and earlier allows user-assisted attackers to execute arbitrary code by overlaying a malicious new window above a file download dialog box, then tricking the user into double-clicking on the "Run" button, aka "link hijacking". | ||||
| CVE-2004-2491 | 1 Opera | 1 Opera Browser | 2026-04-16 | N/A |
| A race condition in Opera web browser 7.53 Build 3850 causes Opera to fill in the address bar before the page has been loaded, which allows remote attackers to spoof the URL in the address bar via the window.open and location.replace HTML parameters, which facilitates phishing attacks. | ||||
| CVE-2004-1490 | 1 Opera | 1 Opera Browser | 2026-04-16 | N/A |
| Opera 7.54 and earlier allows remote attackers to spoof file types in the download dialog via dots and non-breaking spaces (ASCII character code 160) in the (1) Content-Disposition or (2) Content-Type headers. | ||||
| 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-2004-1489 | 1 Opera | 1 Opera Browser | 2026-04-16 | N/A |
| Opera 7.54 and earlier does not properly limit an applet's access to internal Java packages from Sun, which allows remote attackers to gain sensitive information, such as user names and the installation directory. | ||||
| 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-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-2004-0872 | 1 Opera | 1 Opera Browser | 2026-04-16 | N/A |
| Opera does not prevent cookies that are sent over an insecure channel (HTTP) from also being sent over a secure channel (HTTPS/SSL) in the same domain, which could allow remote attackers to steal cookies and conduct unauthorized activities, aka "Cross Security Boundary Cookie Injection." | ||||
| 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-2011-4690 | 1 Opera | 1 Opera Browser | 2025-04-11 | N/A |
| Opera 11.60 and earlier does not prevent capture of data about the times of Same Origin Policy violations during IFRAME loading attempts, which makes it easier for remote attackers to determine whether a document exists in the browser cache via crafted JavaScript code. | ||||
| CVE-2011-4685 | 1 Opera | 1 Opera Browser | 2025-04-11 | N/A |
| Dragonfly in Opera before 11.60 allows remote attackers to cause a denial of service (application crash) via unspecified content on a web page, as demonstrated by forbes.com. | ||||
| CVE-2011-2634 | 1 Opera | 1 Opera Browser | 2025-04-11 | N/A |
| Opera before 11.10 allows remote attackers to hijack (1) searches and (2) customizations via unspecified third party applications. | ||||
| CVE-2011-4684 | 1 Opera | 1 Opera Browser | 2025-04-11 | N/A |
| Opera before 11.60 does not properly handle certificate revocation, which has unspecified impact and remote attack vectors related to "corner cases." | ||||
| CVE-2011-4683 | 1 Opera | 1 Opera Browser | 2025-04-11 | N/A |
| Unspecified vulnerability in Opera before 11.60 has unknown impact and attack vectors, related to a "moderately severe issue." | ||||
| CVE-2011-2633 | 1 Opera | 1 Opera Browser | 2025-04-11 | N/A |
| Unspecified vulnerability in Opera before 11.11 allows remote attackers to cause a denial of service (application crash) via vectors involving a Certificate Revocation List (CRL) file, as demonstrated by the multicert-ca-02.crl file. | ||||
