That's a valid concern however it is another matter.
My suggestion would be:
- get a CVE and assign it to the bug
- be sure to get the right information in the CVE
. about why it is not a flaw in php itself per se but a behavior
change that could introduce a flaw in existing php scripts
. these php scripts were not following our guidance or good practice guide
- Be sure we update the upgrade guide, the NEWS file, the
documentation and the announce to clearly explain and define this
problem and its consequences
Cheers,
