CVE-2020-26965 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
Some websites have a feature "Show Password" where clicking a button will change a password field into a textbook field, revealing the typed password. If, when using a software keyboard that remembers user input, a user typed their password and used that feature, the type of the password field was changed, resulting in a keyboard layout change and the possibility for the software keyboard to remember the typed password. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5.
CVE-2020-26964 2 Google, Mozilla 2 Android, Firefox 2024-11-21 4.0 MEDIUM 6.8 MEDIUM
If the Remote Debugging via USB feature was enabled in Firefox for Android on an Android version prior to Android 6.0, untrusted apps could have connected to the feature and operated with the privileges of the browser to read and interact with web content. The feature was implemented as a unix domain socket, protected by the Android SELinux policy; however, SELinux was not enforced for versions prior to 6.0. This was fixed by removing the Remote Debugging via USB feature from affected devices. *Note: This issue only affected Firefox for Android. Other operating systems are unaffected.*. This vulnerability affects Firefox < 83.
CVE-2020-26963 1 Mozilla 1 Firefox 2024-11-21 4.3 MEDIUM 4.3 MEDIUM
Repeated calls to the history and location interfaces could have been used to hang the browser. This was addressed by introducing rate-limiting to these API calls. This vulnerability affects Firefox < 83.
CVE-2020-26962 1 Mozilla 1 Firefox 2024-11-21 4.3 MEDIUM 6.1 MEDIUM
Cross-origin iframes that contained a login form could have been recognized by the login autofill service, and populated. This could have been used in clickjacking attacks, as well as be read across partitions in dynamic first party isolation. This vulnerability affects Firefox < 83.
CVE-2020-26961 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
When DNS over HTTPS is in use, it intentionally filters RFC1918 and related IP ranges from the responses as these do not make sense coming from a DoH resolver. However when an IPv4 address was mapped through IPv6, these addresses were erroneously let through, leading to a potential DNS Rebinding attack. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5.
CVE-2020-26960 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2024-11-21 9.3 HIGH 8.8 HIGH
If the Compact() method was called on an nsTArray, the array could have been reallocated without updating other pointers, leading to a potential use-after-free and exploitable crash. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5.
CVE-2020-26959 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2024-11-21 6.8 MEDIUM 8.8 HIGH
During browser shutdown, reference decrementing could have occured on a previously freed object, resulting in a use-after-free, memory corruption, and a potentially exploitable crash. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5.
CVE-2020-26958 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2024-11-21 4.3 MEDIUM 6.1 MEDIUM
Firefox did not block execution of scripts with incorrect MIME types when the response was intercepted and cached through a ServiceWorker. This could lead to a cross-site script inclusion vulnerability, or a Content Security Policy bypass. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5.
CVE-2020-26957 1 Mozilla 1 Firefox 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
OneCRL was non-functional in the new Firefox for Android due to a missing service initialization. This could result in a failure to enforce some certificate revocations. *Note: This issue only affected Firefox for Android. Other operating systems are unaffected.*. This vulnerability affects Firefox < 83.
CVE-2020-26956 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2024-11-21 4.3 MEDIUM 6.1 MEDIUM
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-2020-26955 1 Mozilla 1 Firefox 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
When a user downloaded a file in Firefox for Android, if a cookie is set, it would have been re-sent during a subsequent file download operation on the same domain, regardless of whether the original and subsequent request were in private and non-private browsing modes. *Note: This issue only affected Firefox for Android. Other operating systems are unaffected.*. This vulnerability affects Firefox < 83.
CVE-2020-26954 1 Mozilla 1 Firefox 2024-11-21 4.3 MEDIUM 4.3 MEDIUM
When accepting a malicious intent from other installed apps, Firefox for Android accepted manifests from arbitrary file paths and allowed declaring webapp manifests for other origins. This could be used to gain fullscreen access for UI spoofing and could also lead to cross-origin attacks on targeted websites. *Note: This issue only affected Firefox for Android. Other operating systems are unaffected.*. This vulnerability affects Firefox < 83.
CVE-2020-26953 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2024-11-21 4.3 MEDIUM 4.3 MEDIUM
It was possible to cause the browser to enter fullscreen mode without displaying the security UI; thus making it possible to attempt a phishing attack or otherwise confuse the user. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5.
CVE-2020-26952 1 Mozilla 1 Firefox 2024-11-21 9.3 HIGH 8.8 HIGH
Incorrect bookkeeping of functions inlined during JIT compilation could have led to memory corruption and a potentially exploitable crash when handling out-of-memory errors. This vulnerability affects Firefox < 83.
CVE-2020-26951 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2024-11-21 4.3 MEDIUM 6.1 MEDIUM
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. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5.
CVE-2020-26950 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2024-11-21 9.3 HIGH 8.8 HIGH

CVE-2020-25648 4 Fedoraproject, Mozilla, Oracle and 1 more 6 Fedora, Network Security Services, Communications Offline Mediation Controller and 3 more 2024-11-21 5.0 MEDIUM 7.5 HIGH
A flaw was found in the way NSS handled CCS (ChangeCipherSpec) messages in TLS 1.3. This flaw allows a remote attacker to send multiple CCS messages, causing a denial of service for servers compiled with the NSS library. The highest threat from this vulnerability is to system availability. This flaw affects NSS versions before 3.58.
