Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (2.69%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

In the orders section of PrestaShop before 1.7.2.5, an attack is possible after gaining access to a target store with a user role with the rights of at least a Salesman or higher privileges. The attacker can then inject arbitrary PHP objects into the process and abuse an object chain in order to gain Remote Code Execution. This occurs because protection against serialized objects looks for a 0: followed by an integer, but does not consider 0:+ followed by an integer.
