HIGH7.5EPSS 0.05%Docling's JATS XML backend is vulnerable to XML Entity Expansion (XXE) attacks
發布日:2026/5/11修改日:2026/5/18
描述
Docling's JATS XML backend is vulnerable to XML Entity Expansion (XXE) attacks thru 2.61.0. The backend uses etree.parse() to parse XML files without disabling entity resolution. An attacker can craft a malicious XML file containing a nested entity expansion payload (XML Bomb). When processed by Docling, the exponential expansion of entities leads to excessive resource consumption, resulting in a denial of service (DoS) condition on the system running the Docling parser.
