Last modified Jun 17, 2026

CVE-2022-30708 is a high-severity vulnerability rated 8.8/10 on the CVSS scale. Webmin through 1.991, when the Authentic theme is used, allows remote code execution when a user has been manually created (i.e., not created in Virtualmin or Cloudmin). This occurs because settings-editor_write.cgi does not properly restrict the file parameter.. EPSS estimates a 3.27% chance of exploitation in the next 30 days.
