WordPress <= 6.9.1 - Authenticated (Author+) XML External Entity Injection via getID3 Library Media Upload
WordPress core is vulnerable to XML External Entity (XXE) Injection via the bundled getID3 library in all versions up to and including 6.9.1. This is due to the GETID3_LIBXML_OPTIONS constant including the LIBXML_NOENT flag, which enables XML entity substitution during parsing. When WordPress processes media files containing XML metadata (specifically iXML chunks in WAV/RIFF/AVI files), the getID3 library parses the XML with entity substitution enabled, allowing local file disclosure via file:// protocol URIs. This may make it possible for authenticated attackers with Author-level access to read arbitrary files from the server.
