Description

This security bulletin contains information about 1 vulnerability.

1) Improper Preservation of Permissions (CVE-ID: CVE-2025-22620)

CWE-ID: CWE-281 - Improper preservation of permissions

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Green

The vulnerability allows a local user to modify executable files with overly permissive world-writable permissions.

The vulnerability exists due to improper preservation of permissions in gix_worktree_state::checkout and checkout::entry::finalize_entry when checking out executable files with destination_is_initially_empty set to false. A local user can perform a checkout that sets mode 0777 on executable files to modify executable files with overly permissive world-writable permissions.

This affects Unix-like systems, and user interaction is required to perform the checkout operation.
