URLs using “javascript:” have the protocol removed when pasted into the address bar to protect users from cross-site scripting (XSS) attacks, but in certain circumstances this removal was not performed.
Opera through 53 on Android allows Address Bar Spoofing.
Opera for Android before 54.0.2669.49432 is vulnerable to a sandboxed cross-origin iframe bypass attack.
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 co…
Untrusted search path vulnerability in Opera before 10.62 allows local users to gain privileges via a Trojan horse dwmapi.dll file in the current working directory, as demonstrated by a directory that contains a .htm, .m…
Google Chrome detects http content in https web pages only when the top-level frame uses https, which allows man-in-the-middle attackers to execute arbitrary web script, in an https site's context, by modifying an http p…
The HTML parsing engine in Opera before 9.63 allows remote attackers to execute arbitrary code via crafted web pages that trigger an invalid pointer calculation and heap corruption.
Opera 9.51 on Windows XP does not properly handle (1) multipart/mixed e-mail messages with many MIME parts and possibly (2) e-mail messages with many "Content-type: message/rfc822;" headers, which allows remote attackers…
Heap-based buffer overflow in Opera 9.62 on Windows allows remote attackers to execute arbitrary code via a long file:// URI.
The links panel in Opera before 9.62 processes Javascript within the context of the "outermost page" of a frame, which allows remote attackers to inject arbitrary web script or HTML via cross-site scripting (XSS) attacks…

Unspecified vulnerability in Opera before 9.52 on Windows, when registered as a protocol handler, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via unknown vectors in wh…
Opera allows web sites to set cookies for country-specific top-level domains that have DNS A records, such as co.tv, which could allow remote attackers to perform a session fixation attack and hijack a user's HTTP sessio…
Opera, probably before 7.50, sends Referer headers containing https:// URLs in requests for http:// URLs, which allows remote attackers to obtain potentially sensitive information by reading Referer log data.
Unspecified vulnerability in Opera before 9.51 on Windows allows attackers to execute arbitrary code via unknown vectors.
Unspecified vulnerability in Opera before 9.27 has unknown impact and attack vectors related to "keyboard handling of password inputs."
