| CVE-2008-1080 | 1 Opera | 1 Opera Browser | 2025-04-09 | 6.8 MEDIUM | 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-2009-2577 | 1 Opera | 1 Opera Browser | 2025-04-09 | 5.0 MEDIUM | N/A |
| Opera 9.52 and earlier allows remote attackers to cause a denial of service (CPU and memory consumption, and application hang) via a long Unicode string argument to the write method, a related issue to CVE-2009-2479. | |||||
| CVE-2009-2067 | 1 Opera | 1 Opera Browser | 2025-04-09 | 6.8 MEDIUM | N/A |
| Opera 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 page to include an https iframe that references a script file on an http site, related to "HTTP-Intended-but-HTTPS-Loadable (HPIHSL) pages." | |||||
| CVE-2009-2063 | 1 Opera | 1 Opera Browser | 2025-04-09 | 6.8 MEDIUM | N/A |
| Opera, possibly before 9.25, processes a 3xx HTTP CONNECT response before a successful SSL handshake, which allows man-in-the-middle attackers to execute arbitrary web script, in an https site's context, by modifying this CONNECT response to specify a 302 redirect to an arbitrary https web site. | |||||
| CVE-2007-3819 | 1 Opera | 1 Opera Browser | 2025-04-09 | 5.0 MEDIUM | N/A |
| Opera 9.21 allows remote attackers to spoof the data: URI scheme in the address bar via a long URI with trailing whitespace, which prevents the beginning of the URI from being displayed. | |||||
| CVE-2009-3047 | 1 Opera | 1 Opera Browser | 2025-04-09 | 4.3 MEDIUM | N/A |
| Opera before 10.00, when a collapsed address bar is used, does not properly update the domain name from the previously visited site to the currently visited site, which might allow remote attackers to spoof URLs. | |||||
| CVE-2008-4198 | 1 Opera | 1 Opera Browser | 2025-04-09 | 5.0 MEDIUM | N/A |
| Opera before 9.52, when rendering an http page that has loaded an https page into a frame, displays a padlock icon and offers a security information dialog reporting a secure connection, which might allow remote attackers to trick a user into performing unsafe actions on the http page. | |||||
| CVE-2009-3013 | 1 Opera | 1 Opera Browser | 2025-04-09 | 4.3 MEDIUM | N/A |
| Opera 9.52 and earlier, and 10.00 Beta 3 Build 1699, does not properly block data: URIs in Location headers in HTTP responses, which allows remote attackers to conduct cross-site scripting (XSS) attacks via vectors related to (1) injecting a Location header that contains JavaScript sequences in a data:text/html URI or (2) entering a data:text/html URI with JavaScript sequences when specifying the content of a Location header. NOTE: the JavaScript executes outside of the context of the HTTP site. | |||||
| CVE-2007-3929 | 1 Opera | 1 Opera Browser | 2025-04-09 | 9.3 HIGH | 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-2008-4795 | 1 Opera | 1 Opera | 2025-04-09 | 4.3 MEDIUM | N/A |
| 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. | |||||
| CVE-2004-0717 | 3 Linux, Microsoft, Opera | 3 Linux Kernel, Windows, Opera Browser | 2025-04-03 | 7.5 HIGH | 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-2005-4718 | 1 Opera | 1 Opera Browser | 2025-04-03 | 5.0 MEDIUM | N/A |
| Opera 8.02 and earlier allows remote attackers to cause a denial of service (client crash) via (1) a crafted HTML file with a "content: url(0);" style attribute, a "bodyA" tag, a long string, and a "u" tag with a long attribute, as demonstrated by opera.html; and (2) a BGSOUND element with a "margin:-99;" STYLE attribute. | |||||
| CVE-2005-0456 | 1 Opera | 1 Opera Browser | 2025-04-03 | 5.0 MEDIUM | N/A |
| Opera 7.54 and earlier does not properly validate base64 encoded binary data in a data: (RFC 2397) URL, which causes the URL to be obscured in a download dialog, which may allow remote attackers to trick users into executing arbitrary code. | |||||
| CVE-2005-2273 | 1 Opera | 1 Opera Browser | 2025-04-03 | 2.6 LOW | N/A |
| Opera 7.x and 8 before 8.01 does not clearly associate a Javascript dialog box with the web page that generated it, which allows remote attackers to spoof a dialog box from a trusted site and facilitates phishing attacks, aka the "Dialog Origin Spoofing Vulnerability." | |||||
| CVE-2004-1201 | 1 Opera | 1 Opera Browser | 2025-04-03 | 5.0 MEDIUM | N/A |
| Opera 7.54 allows remote attackers to cause a denial of service (application crash from memory exhaustion), as demonstrated using Javascript code that continuously creates nested arrays and then sorts the newly created arrays. | |||||
| CVE-2005-2406 | 1 Opera | 1 Opera Browser | 2025-04-03 | 4.3 MEDIUM | N/A |
| Opera 8.01 allows remote attackers to conduct cross-site scripting (XSS) attacks or modify which files are uploaded by tricking a user into dragging an image that is a "javascript:" URI. | |||||
| CVE-2004-1489 | 1 Opera | 1 Opera Browser | 2025-04-03 | 2.6 LOW | N/A |
| Opera 7.54 and earlier does not properly limit an applet's access to internal Java packages from Sun, which allows remote attackers to gain sensitive information, such as user names and the installation directory. | |||||
| CVE-2004-2491 | 1 Opera | 1 Opera Browser | 2025-04-03 | 2.6 LOW | N/A |
| A race condition in Opera web browser 7.53 Build 3850 causes Opera to fill in the address bar before the page has been loaded, which allows remote attackers to spoof the URL in the address bar via the window.open and location.replace HTML parameters, which facilitates phishing attacks. | |||||
| CVE-2003-1388 | 1 Opera | 1 Opera Browser | 2025-04-03 | 9.3 HIGH | N/A |

| The International Domain Name (IDN) support in Opera 7.54 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. | |||||
