CVE-2020-8417Public exploitNetwork attack vector

Remote code execution via forged snippet import

Published Jan 28, 2020 · Updated Aug 4, 2024

Cross-site request forgery in Code Snippets before 2.14.0 allows remote attackers to execute PHP through a forged import request. The import menu accepts requests without a WordPress nonce or Referer check, while an active value of 1 in imported JSON immediately enables injected code. Exploitation requires a logged-in administrator to visit attacker-controlled content; the injected snippet then runs whenever the site is accessed.
