node-json5 vulnerability
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS
Summary:
JSON5 could allow unintended access to network services or have other
unspecified impact.
Software Description:
- node-json5: JSON for the ES5 era
Details:
It was discovered that the JSON5 parse method incorrectly handled the parsing
of keys named __proto__. An attacker could possibly use this issue to pollute
the prototype of the returned object, setting arbitrary or unexpected keys, and
cause a denial of service, allow unintended access to network services or have
other unspecified impact, depending on the application's use of the module.
