# CVE-2026-86144

## Summary

- **CVE ID:** CVE-2026-86144
- **Severity:** MEDIUM
- **CVSS Score:** 5.6 (CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:C/C:L/I:L/A:L)
- **CWE:** CWE-669
- **Published:** Sep 5, 2026
- **Last Modified:** Sep 8, 2026

## Description

In xinclude in libxml2 before 2.15.4, xmlXIncludeProcess and xmlXIncludeProcessTree do not propagate parseFlags. This has security relevance for, for example, the XML_PARSE_NONET flag, if (without it) a custom resource loader accesses the internet and triggers XML external entity injection, SSRF, or a denial of service (e.g., for an attacker-controlled internet resource that is intentionally slow).

## Affected Products
