CVE-2026-59561Public exploit

Arbitrary command execution via unneutralized directory path

Published Aug 24, 2026 · Updated Aug 24, 2026

OS command injection in Sakura Editor before 2.4.3 allows attackers to execute arbitrary commands through a crafted directory path. The Open Terminal and Open PowerShell actions pass the edited file's current-directory string to PowerShell without neutralizing command syntax. Exploitation requires a victim to open a file from the crafted directory and invoke one of those actions; commands run with that user's privileges.
