"It is, therefore, affected by a vulnerability as referenced in the ALAS2023-2024-614 advisory.

  - Versions of the package pymongo before 4.6.3 are vulnerable to Out-of-bounds Read in the bson module.
    Using the crafted payload the attacker could force the parser to deserialize unmanaged memory. The parser
    tries to interpret bytes next to buffer and throws an exception with string. If the following bytes are
    not printable UTF-8 the parser throws an exception with a single byte. (CVE-2024-21506)

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