Description
A flaw was found in the Python pip package. The pip could allow a local authenticated attacker to bypass security restrictions due to a flaw when installing a package from a Mercurial VCS URL. By sending a specially crafted request, an attacker can inject arbitrary configuration options to the "hg clone" call to modify how and which repository is installed.
Statement
Mercurial is not available in RHEL 8 and 9, so the vulnerability cannot be exploited. Without mercurial installed (the hg command), pip cannot clone and install from hg+http[s] URLs.
