Quick fix
PYSEC-2017-90 — mercurial: upgrade to the fixed version with the command below.
pip install --upgrade 'mercurial>=4.4.1'Details
In Mercurial before 4.4.1, it is possible that a specially malformed repository can cause Git subrepositories to run arbitrary code in the form of a .git/hooks/post-update script checked into the repository. Typical use of Mercurial prevents construction of such repositories, but they can be created programmatically.
