CVE-2009-3013 1 Opera 1 Opera Browser 2026-04-23 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-2009-3044 1 Opera 1 Opera Browser 2026-04-23 N/A
Opera before 10.00 does not properly handle a (1) '\0' character or (2) invalid wildcard character in a domain name in the subject's Common Name (CN) field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority.
CVE-2008-4725 1 Opera 1 Opera Browser 2026-04-23 N/A
Cross-site scripting (XSS) vulnerability in Opera.dll in Opera 9.52 allows remote attackers to inject arbitrary web script or HTML via the query string, which is not properly escaped before storage in the History Search database (aka md.dat), a different vector than CVE-2008-4696. NOTE: some of these issues were addressed before 9.60.
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-2008-4794 1 Opera 1 Opera 2026-04-23 N/A
Opera before 9.62 allows remote attackers to execute arbitrary commands via the History Search results page, a different vulnerability than CVE-2008-4696.
CVE-2008-4698 1 Opera 1 Opera Browser 2026-04-23 N/A
Opera before 9.61 does not properly block scripts during preview of a news feed, which allows remote attackers to create arbitrary new feed subscriptions and read the contents of arbitrary feeds.
CVE-2007-3819 1 Opera 1 Opera Browser 2026-04-23 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-2008-1081 1 Opera 1 Opera Browser 2026-04-23 N/A
Opera before 9.26 allows user-assisted remote attackers to execute arbitrary script via images that contain custom comments, which are treated as script when the user displays the image properties.
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-2008-5683 1 Opera 1 Opera Browser 2026-04-23 N/A
Unspecified vulnerability in Opera before 9.63 allows remote attackers to "reveal random data" via unknown vectors.
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-2007-0126 1 Opera 1 Opera Browser 2026-04-23 N/A
Heap-based buffer overflow in Opera 9.02 allows remote attackers to execute arbitrary code via a JPEG file with an invalid number of index bytes in the Define Huffman Table (DHT) marker.
CVE-2007-0127 1 Opera 1 Opera Browser 2026-04-23 N/A
The Javascript SVG support in Opera before 9.10 does not properly validate object types in a createSVGTransformFromMatrix request, which allows remote attackers to execute arbitrary code via JavaScript code that uses an invalid object in this request that causes a controlled pointer to be referenced during the virtual function call.
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-2008-1761 1 Opera 1 Opera 2026-04-23 N/A
Opera before 9.27 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted newsfeed source, which triggers an invalid memory access.
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-2009-2351 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-2007-1737 1 Opera 1 Opera Browser 2026-04-23 N/A
Opera 9.10 does not check URLs embedded in (1) object or (2) iframe HTML tags against the phishing site blacklist, which allows remote attackers to bypass phishing protection.
CVE-2008-2715 1 Opera 1 Opera Browser 2026-04-23 N/A
Unspecified vulnerability in Opera before 9.5 allows remote attackers to read cross-domain images via HTML CANVAS elements that use the images as patterns.
