Powerline Gitstatus vulnerable to arbitrary code execution
Date: 2022-10
Affected: pip/powerline-gitstatus
Attack vector: rce
Category: vulnerability-disclosure
Severity: High
CVE: CVE-2022-42906
CWE: CWE-77
CWE-94
CVSS: 7.8 (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H)

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.
