8 CVE-2020-12394 2020-05-26 2022-04-26
2.1
 None Local Low Not required None Partial None
A logic flaw in our location bar implementation could have allowed a local attacker to spoof the current location by selecting a different origin and removing focus from the input element. This vulnerability affects Firefox < 76.
9 CVE-2020-12392 22 Dir. Trav. 2020-05-26 2022-04-26
2.1
 None Local Low Not required Partial None None
The 'Copy as cURL' feature of Devtools' network tab did not properly escape the HTTP POST data of a request, which can be controlled by the website. If a user used the 'Copy as cURL' feature and pasted the command into a terminal, it could have resulted in the disclosure of local files. This vulnerability affects Firefox ESR < 68.8, Firefox < 76, and Thunderbird < 68.8.0.
10 CVE-2018-12383 522 2018-10-18 2019-10-03
2.1
 None Local Low Not required Partial None None
If a user saved passwords before Firefox 58 and then later set a master password, an unencrypted copy of these passwords is still accessible. This is because the older stored password file was not deleted when the data was copied to a new format starting in Firefox 58. The new master password is added only on the new file. This could allow the exposure of stored password data outside of user expectations. This vulnerability affects Firefox < 62, Firefox ESR < 60.2.1, and Thunderbird < 60.2.1.
11 CVE-2017-5387 538 2018-06-11 2018-08-07
