CVE-2023-27476 – XML External Entity (XXE) Injection in OWSLib
https://notcve.org/view.php?id=CVE-2023-27476
07 Mar 2023 — OWSLib is a Python package for client programming with Open Geospatial Consortium (OGC) web service interface standards, and their related content models. OWSLib's XML parser (which supports both `lxml` and `xml.etree`) does not disable entity resolution, and could lead to arbitrary file reads from an attacker-controlled XML payload. This affects all XML parsing in the codebase. This issue has been addressed in version 0.28.1. All users are advised to upgrade. • https://github.com/geopython/OWSLib/pull/863/commits/b92687702be9576c0681bb11cad21eb631b9122f • CWE-611: Improper Restriction of XML External Entity Reference •
