CVE-2009-2070 1 Opera 1 Opera Browser 2026-04-23 N/A
Opera displays a cached certificate for a (1) 4xx or (2) 5xx CONNECT response page returned by a proxy server, which allows man-in-the-middle attackers to spoof an arbitrary https site by letting a browser obtain a valid certificate from this site during one request, and then sending the browser a crafted 502 response page upon a subsequent request.
CVE-2009-3045 1 Opera 1 Opera Browser 2026-04-23 N/A
Opera before 10.00 trusts root X.509 certificates signed with the MD2 algorithm, which makes it easier for man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted server certificate.
CVE-2006-6970 1 Opera 1 Opera Browser 2026-04-23 N/A
Opera 9.10 Final allows remote attackers to bypass the Fraud Protection mechanism by adding certain characters to the end of a domain name, as demonstrated by the "." and "/" characters, which is not caught by the blacklist filter.
CVE-2009-3831 2 Microsoft, Opera 2 Windows, Opera Browser 2026-04-23 N/A
Opera before 10.01 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted domain name.
CVE-2009-2540 1 Opera 1 Opera Browser 2026-04-23 N/A
Opera, possibly 9.64 and earlier, allows remote attackers to cause a denial of service (memory consumption) via a large integer value for the length property of a Select object, a related issue to CVE-2009-1692.
CVE-2008-4292 1 Opera 1 Opera Browser 2026-04-23 N/A
Opera before 9.52 does not check the CRL override upon encountering a certificate that lacks a CRL, which has unknown impact and attack vectors. NOTE: it is not clear whether this is a vulnerability, but the vendor included it in a security section of the advisory.
CVE-2007-6523 1 Opera 1 Opera Browser 2026-04-23 N/A
Algorithmic complexity vulnerability in Opera 9.50 beta and 9.x before 9.25 allows remote attackers to cause a denial of service (CPU consumption) via a crafted bitmap (BMP) file that triggers a large number of calculations and checks.
CVE-2006-6955 1 Opera 1 Opera Browser 2026-04-23 N/A
Opera allows remote attackers to cause a denial of service (application crash) via a web page that contains a large number of nested marquee tags, a related issue to CVE-2006-2723.
CVE-2007-6520 1 Opera 1 Opera Browser 2026-04-23 N/A
Opera before 9.25 allows remote attackers to conduct cross-domain scripting attacks via unknown vectors related to plug-ins.
CVE-2007-6524 1 Opera 1 Opera Browser 2026-04-23 N/A
Opera before 9.25 allows remote attackers to obtain potentially sensitive memory contents via a crafted bitmap (BMP) file, as demonstrated using a CANVAS element and JavaScript in an HTML document for copying these contents from 9.50 beta, a related issue to CVE-2008-0420.
CVE-2009-1599 2 Adobe, Opera 2 Acrobat Reader, Opera Browser 2026-04-23 N/A
Opera executes DOM calls in response to a javascript: URI in the target attribute of a submit element within a form contained in an inline PDF file, which might allow remote attackers to bypass intended Adobe Acrobat JavaScript restrictions on accessing the document object, as demonstrated by a web site that permits PDF uploads by untrusted users, and therefore has a shared document.domain between the web site and this javascript: URI. NOTE: the researcher reports that Adobe's position is "a PDF file is active content."
CVE-2008-4196 1 Opera 1 Opera Browser 2026-04-23 N/A
Cross-site scripting (XSS) vulnerability in Opera before 9.52 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.
CVE-2007-1563 1 Opera 1 Opera Browser 2026-04-23 N/A
The FTP protocol implementation in Opera 9.10 allows remote attackers to allows remote servers to force the client to connect to other servers, perform a proxied port scan, or obtain sensitive information by specifying an alternate server address in an FTP PASV response.
CVE-2007-5540 1 Opera 1 Opera Browser 2026-04-23 N/A
Unspecified vulnerability in Opera before 9.24 allows remote attackers to overwrite functions on pages from other domains and bypass the same-origin policy via unknown vectors.
CVE-2009-3048 4 Conectiva, Freebsd, Opera and 1 more 4 Linux, Freebsd, Opera Browser and 1 more 2026-04-23 N/A
Opera before 10.00 on Linux, Solaris, and FreeBSD does not properly implement the "INPUT TYPE=file" functionality, which allows remote attackers to trick a user into uploading an unintended file via vectors involving a "dropped file."
CVE-2007-2022 3 Adobe, Opera, Redhat 3 Flash Player, Opera Browser, Enterprise Linux 2026-04-23 N/A
Adobe Macromedia Flash Player 7 and 9, when used with Opera before 9.20 or Konqueror before 20070613, allows remote attackers to obtain sensitive information (browser keystrokes), which are leaked to the Flash Player applet.
CVE-2007-3929 1 Opera 1 Opera Browser 2026-04-23 N/A
Use-after-free vulnerability in the BitTorrent support in Opera before 9.22 allows user-assisted remote attackers to execute arbitrary code via a crafted header in a torrent file, which leaves a dangling pointer to an invalid object.
CVE-2007-5276 1 Opera 1 Opera Browser 2026-04-23 N/A
Opera 9 drops DNS pins based on failed connections to irrelevant TCP ports, which makes it easier for remote attackers to conduct DNS rebinding attacks, as demonstrated by a port 81 URL in an IMG SRC, when the DNS pin had been established for a session on port 80.
CVE-2008-1080 1 Opera 1 Opera Browser 2026-04-23 N/A
Opera before 9.26 allows user-assisted remote attackers to read arbitrary files by tricking a user into typing the characters of the target filename into a file input.
CVE-2009-0916 1 Opera 1 Opera Browser 2026-04-23 N/A
Unspecified vulnerability in Opera before 9.64 has unknown impact and attack vectors, related to a "moderately severe issue."
