Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Docling versions from 2.13.0 before 2.74.0 are vulnerable to XML external entity attacks in the USPTO patent XML parsers (ICE, Grant v2.5 and Application v1.x). An attacker who can supply a malicious patent XML file could read arbitrary files from the server, make server-side requests, or cause denial of service through entity expansion. Upgrade docling to version 2.74.0 or later. Until then, avoid processing USPTO patent XML from untrusted sources.
