The remote Fedora 37 host has a package installed that is affected by a vulnerability as referenced in the FEDORA-2023-e7297a4aeb advisory.
parse
method of the JSON5 library before and including versions 1.0.1 and 2.2.1 does not restrict parsing of keys named __proto__
, allowing specially crafted strings to pollute the prototype of the resulting object. This vulnerability pollutes the prototype of the object returned by JSON5.parse
and not the global Object prototype, which is the commonly understood definition of Prototype Pollution. However, polluting the prototype of a single object can have significant security impact for an application if the object is later used in trusted operations. This vulnerability could allow an attacker to set arbitrary and unexpected keys on the object returned from JSON5.parse
. The actual impact will depend on how applications utilize the returned object and how they filter unwanted keys, but could include denial of service, cross-site scripting, elevation of privilege, and in extreme cases, remote code execution. JSON5.parse
should restrict parsing of __proto__
keys when parsing JSON strings to objects. As a point of reference, the JSON.parse
method included in JavaScript ignores __proto__
keys. Simply changing JSON5.parse
to JSON.parse
in the examples above mitigates this vulnerability. This vulnerability is patched in json5 versions 1.0.2, 2.2.2, and later. (CVE-2022-46175)Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.

FEDORA-2023-e7297a4aeb advisory.
- JSON5 is an extension to the popular JSON file format that aims to be easier to write and maintain by hand
(e.g. for config files). The `parse` method of the JSON5 library before and including versions 1.0.1 and
2.2.1 does not restrict parsing of keys named `__proto__`, allowing specially crafted strings to pollute
the prototype of the resulting object. This vulnerability pollutes the prototype of the object returned by
`JSON5.parse` and not the global Object prototype, which is the commonly understood definition of
Prototype Pollution. However, polluting the prototype of a single object can have significant security
impact for an application if the object is later used in trusted operations. This vulnerability could
allow an attacker to set arbitrary and unexpected keys on the object returned from `JSON5.parse`. The
actual impact will depend on how applications utilize the returned object and how they filter unwanted
keys, but could include denial of service, cross-site scripting, elevation of privilege, and in extreme
cases, remote code execution. `JSON5.parse` should restrict parsing of `__proto__` keys when parsing JSON
strings to objects. As a point of reference, the `JSON.parse` method included in JavaScript ignores
`__proto__` keys. Simply changing `JSON5.parse` to `JSON.parse` in the examples above mitigates this
vulnerability. This vulnerability is patched in json5 versions 1.0.2, 2.2.2, and later. (CVE-2022-46175)
