CVE-2022-42906

Advisory

Powerline-gitstatus (aka Powerline Gitstatus) before 1.3.2 allows arbitrary code execution. Git repositories can contain per-repository configuration that changes the behavior of git, including running arbitrary commands. When using powerline-gitstatus, changing to a directory automatically runs git commands in order to display information about the current repository in the prompt. If an attacker can convince a user to change their current directory to one controlled by the attacker, such as in a shared filesystem or extracted archive, powerline-gitstatus will run arbitrary commands under the attacker's control.
NOTE: this is similar to CVE-2022-20001.
Affected functions: powerline_gitstatus.segments.GitStatusSegment.get_base_command
