Summary
The EverNoteLoader component in langchain-ai/langchain version 0.3.63 is vulnerable to XML External Entity (XXE) attacks. It parses XML with etree.iterparse() without disabling external entity references, so a crafted XML payload that references local files can expose sensitive data such as /etc/passwd.
Mitigation
The source does not state a fix yet. Check the original advisory for updates.
