CVE-2023-3975Public exploitNetwork attack vector

Arbitrary command execution

Published Jul 27, 2023 · Updated Oct 15, 2024

OS command injection in draw.io before 21.5.0 allows attackers to execute arbitrary commands through an unspecified input vector. The public CNA record identifies the affected repository and CWE-78, but neither it nor the linked 21.5.0 commit discloses which input reaches an operating-system command or how neutralization fails. Exploitation requires user interaction and high-complexity conditions; successful commands run with the affected process's host access.
