Quanos explains that offline catalogs and templates started only locally create no additional attack vector here and need no immediate action. This is not a statement that they contain no PHP.

Scope: Conditional on local-only operation; does not cover online catalog servers.

What users should do

Maintain local-only use. If network-exposed, check the update requirements for online environments.
