CVE-2008-1761 1 Opera 1 Opera 2026-04-23 9.3 HIGH 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-2008-5178 2 Microsoft, Opera 2 Windows, Opera 2026-04-23 9.3 HIGH 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-2007-6522 1 Opera 1 Opera Browser 2026-04-23 4.3 MEDIUM N/A
The rich text editing functionality in Opera before 9.25 allows remote attackers to conduct cross-domain scripting attacks by using designMode to modify contents of pages in other domains.
CVE-2007-1115 1 Opera 1 Opera Browser 2026-04-23 4.3 MEDIUM 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-2009-2070 1 Opera 1 Opera Browser 2026-04-23 6.8 MEDIUM 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-2008-4725 1 Opera 1 Opera Browser 2026-04-23 4.3 MEDIUM 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-2008-3078 1 Opera 1 Opera Browser 2026-04-23 7.8 HIGH 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-2008-3172 1 Opera 1 Opera 2026-04-23 6.8 MEDIUM N/A
Opera allows web sites to set cookies for country-specific top-level domains that have DNS A records, such as co.tv, which could allow remote attackers to perform a session fixation attack and hijack a user's HTTP session, aka "Cross-Site Cooking."
CVE-2009-3046 1 Opera 1 Opera Browser 2026-04-23 5.0 MEDIUM 7.5 HIGH
Opera before 10.00 does not check all intermediate X.509 certificates for revocation, which makes it easier for remote SSL servers to bypass validation of the certificate chain via a revoked certificate.
CVE-2008-4694 1 Opera 1 Opera Browser 2026-04-23 9.3 HIGH N/A
Unspecified vulnerability in Opera before 9.60 allows remote attackers to cause a denial of service (application crash) or execute arbitrary code via a redirect that specifies a crafted URL.

Mozilla Firefox 2.0.0.1 allows remote attackers to bypass the Phishing Protection mechanism by adding certain characters to the end of the domain name, as demonstrated by the "." and "/" characters, which is not caught by the Phishing List blacklist filter.
CVE-2008-2716 1 Opera 1 Opera Browser 2026-04-23 5.0 MEDIUM 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-2008-7245 1 Opera 1 Opera Browser 2026-04-23 5.0 MEDIUM N/A
Opera 9.52 and earlier allows remote attackers to cause a denial of service (unusable browser) by calling the window.print function in a loop, aka a "printing DoS attack," possibly a related issue to CVE-2009-0821.
CVE-2008-4195 1 Opera 1 Opera Browser 2026-04-23 5.0 MEDIUM N/A
Opera before 9.52 does not properly restrict the ability of a framed web page to change the address associated with a different frame, which allows remote attackers to trigger the display of an arbitrary address in a frame via unspecified use of web script.
