Security Advisory: cPanel Mail Sending API Server-Side Request Forgery
This is a security release for cPanel & WHM. Update the product on every affected server to the patched release — `sudo /scripts/upcp --force` — there is no workaround, and unpatched servers remain exposed until updated.

/scripts/upcp --forceWas das unter einer SharedLicense-Lizenz bedeutet
Your SharedLicense license itself is not affected — this is a change in cPanel & WHM software, not in licensing. Apply it on every affected server: sudo /scripts/upcp --force. Licenses keep working through updates; nothing needs re-issuing or re-activating.
