On Android systems, Firefox can load a library from APITRACE_LIB, which is writable by all users and applications. This could allow malicious third party applications to execute a man-in-the-middle attack if a malicious code was written to that location and loaded. *Note: This issue only affects Android. Other operating systems are unaffected.*. This vulnerability affects Firefox < 66. Source: https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-9798 Reference (s):
