| CVE-2004-1157 | 1 Opera | 1 Opera Browser | 2026-04-16 | 7.5 HIGH | 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. | |||||

| 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-2004-2570 | 1 Opera | 1 Opera Browser | 2026-04-16 | 5.0 MEDIUM | 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-2005-3006 | 1 Opera | 1 Opera Browser | 2026-04-16 | 5.0 MEDIUM | N/A |

| CVE-2005-0456 | 1 Opera | 1 Opera Browser | 2026-04-16 | 5.0 MEDIUM | N/A |
| Opera 7.54 and earlier does not properly validate base64 encoded binary data in a data: (RFC 2397) URL, which causes the URL to be obscured in a download dialog, which may allow remote attackers to trick users into executing arbitrary code. | |||||
| CVE-2006-3945 | 2 Microsoft, Opera | 2 Windows Xp, Opera Browser | 2026-04-16 | 5.0 MEDIUM | 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-2005-3699 | 1 Opera | 1 Opera Browser | 2026-04-16 | 5.0 MEDIUM | N/A |
| Opera Web Browser 8.50 and 8.0 through 8.0.2 allows remote attackers to spoof the URL in the status bar via the title in an image in a link to a trusted site within a form to the malicious site. | |||||
| CVE-2005-4210 | 1 Opera | 1 Opera Browser | 2026-04-16 | 5.0 MEDIUM | N/A |
| Opera before 8.51, when running on Windows with Input Method Editor (IME) installed, allows remote attackers to cause a denial of service (persistent application crash) by bookmarking a site with a long title. | |||||
| CVE-2004-0872 | 1 Opera | 1 Opera Browser | 2026-04-16 | 5.0 MEDIUM | 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-2005-0235 | 1 Opera | 1 Opera Browser | 2026-04-16 | 5.0 MEDIUM | 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-2006-1834 | 1 Opera | 1 Opera Browser | 2026-04-16 | 5.1 MEDIUM | 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 | 5.8 MEDIUM | 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 | 5.8 MEDIUM | 6.1 MEDIUM |
| 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-2018-16135 | 1 Opera | 1 Opera Mini | 2025-04-14 | N/A | 6.5 MEDIUM |
| The Opera Mini application 47.1.2249.129326 for Android allows remote attackers to spoof the Location Permission dialog via a crafted web site. | |||||
| CVE-2015-4000 | 12 Apple, Canonical, Debian and 9 more | 25 Iphone Os, Mac Os X, Safari and 22 more | 2025-04-12 | 4.3 MEDIUM | 3.7 LOW |
| 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 | 5.0 MEDIUM | 5.3 MEDIUM |
| 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 | 6.8 MEDIUM | 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. | |||||
