CVE-2016-4075 1 Opera 2 Opera Browser, Opera Mini 2025-04-20 6.1 Medium

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-2018-16135 1 Opera 1 Opera Mini 2025-04-14 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-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-2016-7152 5 Apple, Google, Microsoft and 2 more 6 Safari, Chrome, Edge and 3 more 2025-04-12 N/A
The HTTPS 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-2016-5101 2 Microsoft, Opera 2 Windows, Opera Mail 2025-04-12 N/A
Unspecified vulnerability in Opera Mail before 2016-02-16 on Windows allows user-assisted remote attackers to execute arbitrary code via a crafted e-mail message.
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-2012-3562 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera before 12.00 Beta allows user-assisted remote attackers to cause a denial of service (application crash) via a crafted web page that is not properly handled during a reload, as demonstrated by a "multiple origin camera test" page.
CVE-2011-0684 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera before 11.01 does not properly handle redirections and unspecified other HTTP responses, which allows remote web servers to obtain sufficient access to local files to use these files as page resources, and consequently obtain potentially sensitive information from the contents of the files, via an unknown response manipulation.
CVE-2012-6466 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera before 12.10 does not properly handle incorrect size data in a WebP image, which allows remote attackers to obtain potentially sensitive information from process memory by using a crafted image as the fill pattern for a canvas.

CVE-2014-1870 2 Apple, Opera 2 Mac Os X, Opera Browser 2025-04-11 N/A
Opera before 19 on Mac OS X allows user-assisted remote attackers to spoof the address bar via vectors involving a drag-and-drop operation.
CVE-2008-7297 1 Opera 1 Opera Browser 2025-04-11 N/A
Opera cannot properly restrict modifications to cookies established in HTTPS sessions, which allows man-in-the-middle attackers to overwrite or delete arbitrary cookies via a Set-Cookie header in an HTTP response, related to lack of the HTTP Strict Transport Security (HSTS) includeSubDomains feature, aka a "cookie forcing" issue.
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-2011-0686 1 Opera 1 Opera Browser 2025-04-11 N/A
Unspecified vulnerability in Opera before 11.01 allows remote attackers to cause a denial of service (application crash) via unknown content on a web page, as demonstrated by vkontakte.ru.
