2.7.7 / 2021-02-01

* Security fixes for CVE-2021-21289

  Mechanize `>= v2.0`, `< v2.7.7` allows for OS commands to be injected
  into several classes' methods via implicit use of Ruby's `Kernel.open`
  method. Exploitation is possible only if untrusted input is used as a
  local filename and passed to any of these calls:

  - `Mechanize::CookieJar#load`: since v2.0 (see 208e3ed)
  - `Mechanize::CookieJar#save_as`: since v2.0 (see 5b776a4)
  - `Mechanize#download`: since v2.2 (see dc91667)
  - `Mechanize::Download#save` and `#save!` since v2.1 (see 98b2f51, bd62ff0)
  - `Mechanize::File#save` and `#save_as`: since v2.1 (see 2bf7519)
  - `Mechanize::FileResponse#read_body`: since v2.0 (see 01039f5)

  for more information.
