This issue was patched in RHSA-2024:0430.

NVD Description

Note: Versions mentioned in the description apply only to the upstream platform-python package and not the platform-python package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

The email module of Python through 3.11.3 incorrectly parses e-mail addresses that contain a special character. The wrong portion of an RFC2822 header is identified as the value of the addr-spec. In some applications, an attacker can bypass a protection mechanism in which application access is granted only after verifying receipt of e-mail to a specific domain (e.g., only @company.example.com addresses may be used for signup). This occurs in email/_parseaddr.py in recent versions of Python.
