I use the Fabrik extension on several sites (J5 and J6). HTProtect is advising me that Fabrik 4.7.2 is "vulnerable" and to upgrade to 4.7.3. There does not seem to be any such version available from the developers, 4.7.2 seems the latest and mysites.guru states "Updated 22 August 2026: Fabrik is now on 4.7.2". Please advise?
