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. • https://bugzilla.mozilla.org/show_bug.cgi?id=1657026 https://www.mozilla.org/security/advisories/mfsa2020-50 •

CVSS: 6.5EPSS: 0%CPEs: 3EXPL: 0CVE-2020-26965 – Mozilla: Software keyboards may have remembered typed passwords
https://notcve.org/view.php?id=CVE-2020-26965
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. Algunos sitios web presentan una funcionalidad "Show Password" donde al hacer clic en un botón se cambiará un campo de contraseña en un campo textbook, divulgando la contraseña escrita. Si, al usar un teclado de software que recuerda la entrada del usuario, un usuario escribió su contraseña y usó esa funcionalidad, se cambió el tipo de campo de contraseña, resultando en un cambio de distribución del teclado y la posibilidad de que el teclado de software recuerde la contraseña escrita. • https://bugzilla.mozilla.org/show_bug.cgi?id=1661617 https://www.mozilla.org/security/advisories/mfsa2020-50 https://www.mozilla.org/security/advisories/mfsa2020-51 https://www.mozilla.org/security/advisories/mfsa2020-52 https://access.redhat.com/security/cve/CVE-2020-26965 https://bugzilla.redhat.com/show_bug.cgi?id=1898739 • CWE-212: Improper Removal of Sensitive Information Before Storage or Transfer •

https://notcve.org/view.php?id=CVE-2020-26958
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. Firefox no bloqueó una ejecución de scripts con tipos MIME incorrectos cuando la respuesta fue interceptada y almacenada en caché por medio de un ServiceWorker.
