Severity
8.7 (High) - CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N
Summary
Craft CMS versions from 4.0.0-RC1 before 4.18.2 and from 5.0.0-RC1 before 5.10.6 contain an authenticated remote code execution vulnerability in control panel element-search condition handling. A JSON cleanse bypass in condition.config allows Yii behavior/event configuration keys to be interpreted after decoding, enabling command execution as the PHP/web user.
