Synopsis

The version of PHP running on the remote web server is affected by an email header injection vulnerability.

Description

According to its self-reported version number, the version of PHP running on the remote web server is prior to 7.3.28.
It is, therefore affected by an email header injection vulnerability, due to a failure to properly handle CR-LF sequences in header fields. An unauthenticated, remote attacker can exploit this, by inserting line feed characters into email headers, to gain full control of email header content.

Solution

Upgrade to PHP version 7.3.28 or later.
