The subject alternative name specified for this certificate. This is a comma-separated list of subject alternative names. Each entry begins with a string identifying the kind of the subject alternative name followed by a colon and the value associated with the entry. Earlier versions of Node.js incorrectly assumed that it is safe to split this property at the two-character sequence `', '` (see [CVE-2021-44532](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-44532)). However, both malicious and legitimate certificates can contain subject alternative names that include this sequence when represented as a string. After the prefix denoting the type of the entry, the remainder of each entry might be enclosed in quotes to indicate that the value is a JSON string literal. For backward compatibility, Node.js only uses JSON string literals within this property when necessary to avoid ambiguity. Third-party code should be prepared to handle both possible entry formats.
