| CVE | Vendors | Products | Updated | CVSS v3.1 |
|---|---|---|---|---|
| CVE-2008-4200 | 1 Opera | 1 Opera Browser | 2026-04-23 | N/A |
| Opera before 9.52 does not ensure that the address field of a news feed represents the feed's actual URL, which allows remote attackers to change this field to display the URL of a page containing web script controlled by the attacker. | ||||
| 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-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-2008-5682 | 1 Opera | 1 Opera Browser | 2026-04-23 | N/A |
| Cross-site scripting (XSS) vulnerability in Opera before 9.63 allows remote attackers to inject arbitrary web script or HTML via built-in XSLT templates. | ||||
| 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-2007-3142 | 1 Opera | 1 Opera Browser | 2026-04-23 | N/A |
| Visual truncation vulnerability in Opera 9.21 allows remote attackers to spoof the address bar and possibly conduct phishing attacks via a long hostname, which is truncated after 34 characters, as demonstrated by a phishing attack using HTTP Basic Authentication. | ||||
| 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-2008-4698 | 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-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-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-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-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-2008-3078 | 1 Opera | 1 Opera Browser | 2026-04-23 | N/A |
| Opera before 9.51 does not properly manage memory within functions supporting the CANVAS element, which allows remote attackers to read uninitialized memory contents by using JavaScript to read a canvas image. | ||||
| 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-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-2007-1115 | 1 Opera | 1 Opera Browser | 2026-04-23 | N/A |
| The child frames in Opera 9 before 9.20 inherit the default charset from the parent window when a charset is not specified in an HTTP Content-Type header or META tag, which allows remote attackers to conduct cross-site scripting (XSS) attacks, as demonstrated using the UTF-7 character set. | ||||
| CVE-2009-3266 | 1 Opera | 1 Opera Browser | 2026-04-23 | N/A |
| Opera before 10.01 does not properly restrict HTML in a (1) RSS or (2) Atom feed, which allows remote attackers to conduct cross-site scripting (XSS) attacks, and conduct cross-zone scripting attacks involving the Feed Subscription Page to read feeds or create feed subscriptions, via a crafted feed, related to the rendering of the application/rss+xml content type as "scripted content." | ||||
| 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-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-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. | ||||
