| CVE-2020-26956 | Med | 0.40 | 6.1 | 0.01 | Dec 9, 2020 | In some cases, removing HTML elements during sanitization would keep existing SVG event handlers and therefore lead to XSS. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5. | ||
| CVE-2020-26951 | Med | 0.40 | 6.1 | 0.01 | Dec 9, 2020 | A parsing and event loading mismatch in Firefox's SVG code could have allowed load events to fire, even after sanitization. An attacker already capable of exploiting an XSS vulnerability in privileged internal pages could have used this attack to bypass our built-in sanitizer.… | ||
| 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-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-2019-11715 | Med | 0.40 | 6.1 | 0.01 | 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-2017-5466 | Med | 0.40 | 6.1 | 0.02 | Jun 11, 2018 | If a page is loaded from an original site through a hyperlink and contains a redirect to a "data:text/html" URL, triggering a reload will run the reloaded "data:text/html" page with its origin set incorrectly. This allows for a cross-site scripting (XSS) attack. This… | ||
| CVE-2016-9895 | Med | 0.40 | 6.1 | 0.02 | Jun 11, 2018 | Event handlers on "marquee" elements were executed despite a strict Content Security Policy (CSP) that disallowed inline JavaScript. This vulnerability affects Firefox < 50.1, Firefox ESR < 45.6, and Thunderbird < 45.6. | ||
| CVE-2014-1530 | Med | 0.40 | 6.1 | 0.02 | Apr 30, 2014 | The docshell implementation in Mozilla Firefox before 29.0, Firefox ESR 24.x before 24.5, Thunderbird before 24.5, and SeaMonkey before 2.26 allows remote attackers to trigger the loading of a URL with a spoofed baseURI property, and conduct cross-site scripting (XSS) attacks,… | ||
| CVE-2016-9074 | Med | 0.39 | 5.9 | 0.02 | Jun 11, 2018 | An existing mitigation of timing side-channel attacks is insufficient in some circumstances. This issue is addressed in Network Security Services (NSS) 3.26.1. This vulnerability affects Thunderbird < 45.5, Firefox ESR < 45.5, and Firefox < 50. | ||
| CVE-2013-6673 | Med | 0.39 | 5.9 | 0.03 | Dec 11, 2013 | Mozilla Firefox before 26.0, Firefox ESR 24.x before 24.2, Thunderbird before 24.2, and SeaMonkey before 2.23 do not recognize a user's removal of trust from an EV X.509 certificate, which makes it easier for man-in-the-middle attackers to spoof SSL servers in opportunistic… | ||
| CVE-2009-2408 | Med | 0.39 | 5.9 | 0.06 | Jul 30, 2009 | Mozilla Network Security Services (NSS) before 3.12.3, Firefox before 3.0.13, Thunderbird before 2.0.0.23, and SeaMonkey before 1.1.18 do not properly handle a '\0' character in a domain name in the subject's Common Name (CN) field of an X.509 certificate, which allows… | ||
| CVE-2025-4082 | Med | 0.38 | 5.9 | 0.00 | Apr 29, 2025 | Modification of specific WebGL shader attributes could trigger an out-of-bounds read, which, when chained with other vulnerabilities, could be used to escalate privileges. *This bug only affects Thunderbird for macOS. Other versions of Thunderbird are unaffected.*. This… | ||
| CVE-2025-1015 | Med | 0.38 | 5.4 | 0.01 | Feb 4, 2025 | The Thunderbird Address Book URI fields contained unsanitized links. This could be used by an attacker to create and export an address book containing a malicious payload in a field. For example, in the “Other” field of the Instant Messaging section. If another user imported… | ||
| CVE-2022-22746 | Med | 0.38 | 5.9 | 0.01 | Dec 22, 2022 | A race condition could have allowed bypassing the fullscreen notification which could have lead to a fullscreen window spoof being unnoticed.*This bug only affects Firefox for Windows. Other operating systems are unaffected.*. This vulnerability affects Firefox ESR < 91.5,… | ||
| CVE-2021-38502 | Med | 0.38 | 5.9 | 0.01 | Nov 3, 2021 | Thunderbird ignored the configuration to require STARTTLS security for an SMTP connection. A MITM could perform a downgrade attack to intercept transmitted messages, or could take control of the authenticated session to execute SMTP commands chosen by the MITM. If an unprotected… | ||
| CVE-2021-29969 | Med | 0.38 | 5.9 | 0.01 | Aug 5, 2021 | If Thunderbird was configured to use STARTTLS for an IMAP connection, and an attacker injected IMAP server responses prior to the completion of the STARTTLS handshake, then Thunderbird didn't ignore the injected data. This could have resulted in Thunderbird showing incorrect… |
