magento 1 – Magento1 SUPEE-11086 Potential Problems?

The description of the hotfix SUPEE-11086 is as follows:

SUPEE-11086, Magento Commerce and Open Source contain
several security enhancements that help to shut down remote code execution
(RCE), intersite scripting (XSS), intersite query forgery (CSRF)
and other vulnerabilities.

Also includes a fix for SQL Injection with CVSSv3 Severity: 9.0

An unauthenticated user can execute arbitrary code via SQL
Injection vulnerability, which causes leakage of sensitive data.

Are there any problems or problems that we can expect from this fix?
