A security issue has been discovered that we consider to be of a high severity,
and as a result we have decided there is a need to release an immediate patch
for it.
Although not related to the new release, it is unfortunate timing
so soon after the release, but we take security very seriously and so if an
issue becomes apparent to us, we will always issue a patch immediately for it as
our track record with patches in recent years demonstrates.
Applying the
patch is very simple. It's just a single file to update. There are separate
versions of the file for each release of WHMCS from V4.0 up to the very latest
V5.0 release. The patch download consists of a single file which just needs to
be unzipped, and then uploaded to the /includes/ folder replacing the existing
file. Download links are as follows:
If
you have any questions or need any assistance applying the patch, please do not
hesitate to contact us.
We apologize for the inconvenience.
