# Telerik Document Processing: crafted DOCX or RTF file crashes or hangs the host

Telerik Document Processing Libraries before 2026.3.1027 have uncontrolled recursion and infinite loop flaws in RadWordsProcessing. An unauthenticated attacker who supplies a crafted DOCX, DOC, RTF or HTML document can terminate or hang the process that parses it.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the Telerik Document Processing Libraries version in your project's package references or lock files against `2026.3.1027`.
- Find code paths where RadWordsProcessing parses user-uploaded DOCX, DOC, RTF or HTML files.

## Fix

- Upgrade Telerik Document Processing Libraries to `2026.3.1027` or later.

## Timeline

- 2026-10-28T13:33:01+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-118035

## From the sources

In Progress® Telerik® Document Processing Libraries prior to version 2026.3.1027, uncontrolled recursion, inefficient algorithmic complexity and infinite loop vulnerabilities in RadWordsProcessing allow an unauthenticated attacker to terminate or hang the host process via a crafted DOCX, DOC, RTF or HTML document.
