| CVE-2020-15677 | Med | 0.40 | 6.1 | 0.02 | Oct 1, 2020 | By exploiting an Open Redirect vulnerability on a website, an attacker could have spoofed the site displayed in the download file dialog to show the original site (the one suffering from the open redirect) rather than the site the file was actually downloaded from. This… | ||
| CVE-2020-15676 | Med | 0.40 | 6.1 | 0.02 | Oct 1, 2020 | Firefox sometimes ran the onload handler for SVG elements that the DOM sanitizer decided to remove, resulting in JavaScript being executed after pasting attacker-controlled data into a contenteditable element. This vulnerability affects Firefox < 81, Thunderbird < 78.3, and… | ||
| CVE-2020-6798 | Med | 0.40 | 6.1 | 0.02 | Mar 2, 2020 | If a template tag was used in a select tag, the parser could be confused and allow JavaScript parsing and execution when it should not be allowed. A site that relied on the browser behaving correctly could suffer a cross-site scripting vulnerability as a result. In general, this… | ||
| CVE-2011-2670 | Med | 0.40 | 6.1 | 0.01 | Jan 13, 2020 | Mozilla Firefox before 3.6 is vulnerable to XSS via the rendering of Cascading Style Sheets | ||
| CVE-2019-17022 | Med | 0.40 | 6.1 | 0.02 | Jan 8, 2020 | When pasting a <style> tag from the clipboard into a rich text editor, the CSS sanitizer does not escape < and > characters. Because the resulting string is pasted directly into the text node of the element this does not result in a direct injection into the webpage;… | ||
| CVE-2019-17016 | Med | 0.40 | 6.1 | 0.02 | Jan 8, 2020 | When pasting a <style> tag from the clipboard into a rich text editor, the CSS sanitizer incorrectly rewrites a @namespace rule. This could allow for injection into certain types of websites resulting in data exfiltration. This vulnerability affects Firefox ESR < 68.4 and… | ||
| CVE-2019-17001 | Med | 0.40 | 6.1 | 0.01 | Jan 8, 2020 | A Content-Security-Policy that blocks in-line scripts could be bypassed using an object tag to execute JavaScript in the protected document (cross-site scripting). This is a separate bypass from CVE-2019-17000.*Note: This flaw only affected Firefox 69 and was not present in… | ||
| CVE-2019-17000 | Med | 0.40 | 6.1 | 0.01 | Jan 8, 2020 | An object tag with a data URI did not correctly inherit the document's Content Security Policy. This allowed a CSP bypass in a cross-origin frame if the document's policy explicitly allowed data: URIs. This vulnerability affects Firefox < 70. | ||
| CVE-2019-11763 | Med | 0.40 | 6.1 | 0.01 | Jan 8, 2020 | Failure to correctly handle null bytes when processing HTML entities resulted in Firefox incorrectly parsing these entities. This could have led to HTML comment text being treated as HTML which could have led to XSS in a web application under certain conditions. It could have… | ||
| CVE-2019-11762 | Med | 0.40 | 6.1 | 0.01 | Jan 8, 2020 | If two same-origin documents set document.domain differently to become cross-origin, it was possible for them to call arbitrary DOM methods/getters/setters on the now-cross-origin window. This vulnerability affects Firefox < 70, Thunderbird < 68.2, and Firefox ESR < 68.2. | ||
| CVE-2019-11744 | Med | 0.40 | 6.1 | 0.01 | Sep 27, 2019 | Some HTML elements, such as <title> and <textarea>, can contain literal angle brackets without treating them as markup. It is possible to pass a literal closing tag to .innerHTML on these elements, and subsequent content after that will be parsed as if it were… | ||
| CVE-2019-11741 | Med | 0.40 | 6.1 | 0.01 | Sep 27, 2019 | A compromised sandboxed content process can perform a Universal Cross-site Scripting (UXSS) attack on content from any site it can cause to be loaded in the same process. Because addons.mozilla.org and accounts.firefox.com have close ties to the Firefox product, malicious… | ||
| CVE-2019-11724 | Med | 0.40 | 6.1 | 0.01 | Jul 23, 2019 | Application permissions give additional remote troubleshooting permission to the site input.mozilla.org, which has been retired and now redirects to another site. This additional permission is unnecessary and is a potential vector for malicious attacks. This vulnerability… | ||
| CVE-2019-11720 | Med | 0.40 | 6.1 | 0.01 | Jul 23, 2019 | Some unicode characters are incorrectly treated as whitespace during the parsing of web content instead of triggering parsing errors. This allows malicious code to then be processed, evading cross-site scripting (XSS) filtering. This vulnerability affects Firefox < 68. | ||
| CVE-2019-11715 | Med | 0.40 | 6.1 | 0.02 | Jul 23, 2019 | Due to an error while parsing page content, it is possible for properly sanitized user input to be misinterpreted and lead to XSS hazards on web sites in certain circumstances. This vulnerability affects Firefox ESR < 60.8, Firefox < 68, and Thunderbird < 60.8. | ||
| CVE-2019-11701 | Med | 0.40 | 6.1 | 0.01 | Jul 23, 2019 | The default webcal: protocol handler will load a web site vulnerable to cross-site scripting (XSS) attacks. This default was left in place as a legacy feature and has now been removed. *Note: this issue only affects users with an account on the vulnerable service. Other users… | ||
| CVE-2018-5124 | Med | 0.40 | 6.1 | 0.01 | Apr 26, 2019 | Unsanitized output in the browser UI leaves HTML tags in place and can result in arbitrary code execution in Firefox before version 58.0.1. | ||
| CVE-2018-5176 | Med | 0.40 | 6.1 | 0.02 | Jun 11, 2018 | The JSON Viewer displays clickable hyperlinks for strings that are parseable as URLs, including "javascript:" links. If a JSON file contains malicious JavaScript script embedded as "javascript:" links, users may be tricked into clicking and running this code in the context of… | ||
| CVE-2018-5175 | Med | 0.40 | 6.1 | 0.02 | Jun 11, 2018 | A mechanism to bypass Content Security Policy (CSP) protections on sites that have a "script-src" policy of "'strict-dynamic'". If a target website contains an HTML injection flaw an attacker could inject a reference to a copy of the "require.js" library that is part of… | ||
| CVE-2018-5164 | Med | 0.40 | 6.1 | 0.02 | Jun 11, 2018 | Content Security Policy (CSP) is not applied correctly to all parts of multipart content sent with the "multipart/x-mixed-replace" MIME type. This could allow for script to run where CSP should block it, allowing for cross-site scripting (XSS) and other attacks. This… |
