CyberRota Analysis
AI-GeneratedThe vulnerability affects the docx4j library, specifically in its handling of style inheritance in DOCX files, which can lead to unbounded recursion and a StackOverflowError when processing documents with mutually based styles. This can result in denial of service, particularly during server-side document conversion or table-of-contents processing. Organizations using versions prior to 11.5.14 should prioritize updating to mitigate potential service disruptions.

Original NVD Description
docx4j is an open source Java library for creating, editing, and saving OpenXML packages, including DOCX, PPTX, and XLSX files. Prior to 11.5.14, PropertyResolver and adjacent helpers recursively follow the WordprocessingML w:basedOn style inheritance chain without cycle detection. A well-formed DOCX containing mutually based styles causes unbounded recursion in PropertyResolver.fillPPrStack and related effective-style resolution paths, resulting in StackOverflowError. Server-side conversion and table-of-contents processing of an untrusted document can terminate a worker thread, degrade a thread pool, or deny service, although isolation in disposable workers or safe containment of StackOverflowError can reduce the practical effect. The fix adds cyclic-style tracking and CyclicStylesException handling. This issue is fixed in version 11.5.14.
