CVE-2008-2716 1 Opera 1 Opera Browser 2026-04-23 N/A
Unspecified vulnerability in Opera before 9.5 allows remote attackers to spoof the contents of trusted frames on the same parent page by modifying the location, which can facilitate phishing attacks.
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-2009-3049 1 Opera 1 Opera Browser 2026-04-23 N/A
Opera before 10.00 does not properly display all characters in Internationalized Domain Names (IDN) in the address bar, which allows remote attackers to spoof URLs and conduct phishing attacks, related to Unicode and Punycode.
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-2007-2274 1 Opera 1 Opera Browser 2026-04-23 N/A
The BitTorrent implementation in Opera 9.2 allows remote attackers to cause a denial of service (CPU consumption and application crash) via a malformed torrent file. NOTE: the original disclosure refers to this as a memory leak, but it is not certain.
CVE-2007-2809 1 Opera 1 Opera Browser 2026-04-23 N/A
Buffer overflow in the transfer manager in Opera before 9.21 for Windows allows user-assisted remote attackers to execute arbitrary code via a crafted torrent file. NOTE: due to the lack of details, it is not clear if this is the same issue as CVE-2007-2274.
CVE-2009-2351 1 Opera 1 Opera Browser 2026-04-23 N/A
Opera 9.52 and earlier does not block javascript: URIs in Refresh headers in HTTP responses, which allows remote attackers to conduct cross-site scripting (XSS) attacks via vectors related to (1) injecting a Refresh header or (2) specifying the content of a Refresh header, a related issue to CVE-2009-1312. NOTE: it was later reported that 10.00 Beta 3 Build 1699 is also affected.
CVE-2007-6521 1 Opera 1 Opera Browser 2026-04-23 N/A
Unspecified vulnerability in Opera before 9.25 allows remote attackers to execute arbitrary code via crafted TLS certificates.
CVE-2009-2059 1 Opera 1 Opera Browser 2026-04-23 N/A
Opera, possibly before 9.25, uses the HTTP Host header to determine the context of a document provided in a (1) 4xx or (2) 5xx CONNECT response from a proxy server, which allows man-in-the-middle attackers to execute arbitrary web script by modifying this CONNECT response, aka an "SSL tampering" attack.
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-2008-5178 2 Microsoft, Opera 2 Windows, Opera 2026-04-23 N/A
Heap-based buffer overflow in Opera 9.62 on Windows allows remote attackers to execute arbitrary code via a long file:// URI. NOTE: this might overlap CVE-2008-5680.
CVE-2006-4819 1 Opera 1 Opera Browser 2026-04-23 N/A
Heap-based buffer overflow in Opera 9.0 and 9.01 allows remote attackers to execute arbitrary code via a long URL in a tag (long link address).
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-2008-4197 5 Freebsd, Linux, Microsoft and 2 more 5 Freebsd, Linux Kernel, Windows and 2 more 2026-04-23 8.8 High
Opera before 9.52 on Windows, Linux, FreeBSD, and Solaris, when processing custom shortcut and menu commands, can produce argument strings that contain uninitialized memory, which might allow user-assisted remote attackers to execute arbitrary code or conduct other attacks via vectors related to activation of a shortcut.
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-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-2008-4293 2 Microsoft, Opera 2 Windows, Opera 2026-04-23 N/A
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 which Opera is launched by other applications.
CVE-2008-4697 1 Opera 1 Opera Browser 2026-04-23 N/A
The Fast Forward feature in Opera before 9.61, when a page is located in a frame, executes a javascript: URL in the context of the outermost page instead of the page that contains this URL, which allows remote attackers to conduct cross-site scripting (XSS) attacks.
CVE-2007-5274 4 Mozilla, Opera, Redhat and 1 more 6 Firefox, Opera Browser, Rhel Extras and 3 more 2026-04-23 N/A
Sun Java Runtime Environment (JRE) in JDK and JRE 6 Update 2 and earlier, JDK and JRE 5.0 Update 12 and earlier, SDK and JRE 1.4.2_15 and earlier, and SDK and JRE 1.3.1_20 and earlier, when Firefox or Opera is used, allows remote attackers to violate the security model for JavaScript outbound connections via a multi-pin DNS rebinding attack dependent on the LiveConnect API, in which JavaScript download relies on DNS resolution by the browser, but JavaScript socket operations rely on separate DNS resolution by a Java Virtual Machine (JVM), a different issue than CVE-2007-5273. NOTE: this is similar to CVE-2007-5232.
CVE-2007-5476 3 Adobe, Apple, Opera 3 Flash Player, Mac Os X, Opera Browser 2026-04-23 N/A
Unspecified vulnerability in Adobe Flash Player 9.0.47.0 and earlier, when running on Opera before 9.24 on Mac OS X, has unknown "Highly Severe" impact and unknown attack vectors.
