"It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2023-252 advisory.

  - 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. (CVE-2023-27043)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
