What do these updates contain
Change in default algorithm
- The default encryption algorithm in ColdFusion changes from CFMX_COMPAT to another algorithm for seven encryption functions.
- Use the new JVM argument -Dcoldfusion.encryption.useCFMX_COMPATAsDefault=TRUE to revert the change. By default, the value is False,
- The flag -Dcoldfusion.encryption.useCFMX_COMPATAsDefault will be supported in future security updates for the 2023 and 2021 releases of Adobe ColdFusion.
CFdocument access control issues
We've introduced a new JVM flag: -Dcfdocument.metahttpequivrefresh.localfile=TRUE. This flag allows you to call the URL or location passed in the HTML meta tag. By default, the value is FALSE.
However, in the next major release of ColdFusion, we WILL remove the flag.
