github.com/snapcore/snapd is vulnerable to Incorrect Permission Assignment for Critical Resource. The vulnerability is due to the improper restriction of writes to the $HOME/bin path. An attacker can execute arbitrary scripts outside of the expected snap sandbox, potentially allowing them to escape confinement by convincing a user to install a malicious snap that utilizes the ‘home’ plug.
