Description: LogicalDOC Community Edition through 9.3 contains a server-side request forgery vulnerability in the default-enabled XMLConverter that fetches xml-stylesheet href URLs without scheme or host allowlisting. Authenticated users can upload XML documents whose stylesheet href points to internal http, ftp, file, or jar URLs, forcing server requests and applying attacker-controlled XSLT during conversion.
