डिफ़ॉल्ट अपडेट कमांड

cd /usr/src && rm -f csf.tgz && wget https://download.configserver.com/csf.tgz && tar -xzf csf.tgz && cd csf && sh install.sh && csf -r

SharedLicense लाइसेंस के तहत इसका अर्थ

Your SharedLicense license itself is not affected — this is a change in cPanel & WHM software, not in licensing. Reinstall CSF from the latest ConfigServer package (csf.tgz) and run csf -r. Licenses keep working through updates; nothing needs re-issuing or re-activating.

Security fixes This security release resolves several vulnerabilities in CSF (CPANEL-54191, CPANEL-55183, CPANEL-54192, CPANEL-55265). It also includes several firewall reliability fixes for AlmaLinux 10, Debian, and Ubuntu. For a full list of changes, read the ConfigServer Security & Firewall (CSF) change log.
