|---|---|---|---|---|
| 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-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-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-2003-0593 | 1 Opera | 1 Opera Browser | 2026-04-16 | N/A |
| Opera allows remote attackers to bypass intended cookie access restrictions on a web application via "%2e%2e" (encoded dot dot) directory traversal sequences in a URL, which causes Opera to send the cookie outside the specified URL subsets, e.g. to a vulnerable application that runs on the same server as the target application. | ||||
| 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-2004-0717 | 3 Linux, Microsoft, Opera | 3 Linux Kernel, Windows, Opera Browser | 2026-04-16 | N/A |
| Opera 7.51 for Windows and 7.50 for Linux does not properly prevent a frame in one domain from injecting content into a frame that belongs to another domain, which facilitates web site spoofing and other attacks, aka the frame injection vulnerability. | ||||
| 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-2005-1669 | 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-2005-3946 | 1 Opera | 1 Opera Browser | 2026-04-16 | N/A |
| Opera 8.50 allows remote attackers to cause a denial of service (crash) via a Java applet with a large string argument to the removeMember JNI method for the com.opera.JSObject class. | ||||
| CVE-2004-1491 | 4 Gentoo, Kde, Opera and 1 more | 4 Linux, Kde, Opera Browser and 1 more | 2026-04-16 | N/A |
| Opera 7.54 and earlier uses kfmclient exec to handle unknown MIME types, which allows remote attackers to execute arbitrary code via a shortcut or launcher that contains an Exec entry. | ||||
| 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-2016-4075 | 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-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-2011-4681 | 1 Opera | 1 Opera Browser | 2025-04-11 | N/A |
| Opera before 11.60 does not properly consider the number of . (dot) characters that conventionally exist in domain names of different top-level domains, which allows remote attackers to bypass the Same Origin Policy by leveraging access to a different domain name in the same top-level domain, as demonstrated by the .no or .uk domain. | ||||
| CVE-2010-2455 | 1 Opera | 1 Opera Browser | 2025-04-11 | N/A |
| Opera does not properly manage the address bar between the request to open a URL and the retrieval of the new document's content, which might allow remote attackers to conduct spoofing attacks via a crafted HTML document, a related issue to CVE-2010-1206. | ||||
| CVE-2012-3557 | 1 Opera | 1 Opera Browser | 2025-04-11 | N/A |
| Opera before 11.65 does not properly restrict the reading of JSON strings, which allows remote attackers to perform cross-domain loading of JSON resources and consequently obtain sensitive information via a crafted web site. | ||||
| 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-2012-3563 | 1 Opera | 1 Opera Browser | 2025-04-11 | N/A |
| Opera before 12.00 Beta allows remote attackers to cause a denial of service (application crash) via a web page that contains invalid character encodings. | ||||
| CVE-2011-2621 | 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 related to form layout. | ||||
