How to fix?

There is no fixed version for RHEL:7 satellite/iop-vmaas-rhel9.

NVD Description

Note: Versions mentioned in the description apply only to the upstream satellite/iop-vmaas-rhel9 package and not the satellite/iop-vmaas-rhel9 package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

Python-Multipart is a streaming multipart parser for Python. Prior to 0.0.30, QuerystringParser treated ; as a field separator in application/x-www-form-urlencoded bodies, in addition to &. The WHATWG URL standard, modern browsers, and Python's urllib.parse (since the CVE-2021-23336 fix) treat only & as a separator. This creates a parser differential: the same bytes are tokenized into different fields than a WHATWG compliant intermediary would produce, allowing an attacker to smuggle extra form fields past an upstream body inspecting component. This vulnerability is fixed in 0.0.30.
