CVE-2022-44089Public exploitNetwork attack vector

Unauthenticated code execution via IS_GETCACHE injection

Published Nov 10, 2022 · Updated Jul 9, 2026

Remote code execution in ESPCMS P8.21120101 allows remote attackers to execute arbitrary PHP code through the IS_GETCACHE component. The IS_GETCACHE parameter accepts injected PHP syntax that is written into a PHP file and then executed by the application. Remote attackers are scored as requiring no privileges, although the public demonstration uses a logged-in management session; successful execution can compromise confidentiality, integrity, and availability.
