`xml.parsers.expat` and `xml.etree.ElementTree` use insufficient entropy for Expat hash-flooding protection, which allows a crafted XML document to trigger hash flooding.\r\n\r\nFully mitigating this vulnerability requires both updating libexpat to 2.8.0 or later and applying this patch.

The vulnerability CVE-2026-7210 in CPython arises from insufficient entropy in the hash-flooding protection mechanism of the xml.parsers.expat and xml.etree.ElementTree modules. This weakness allows an attacker to craft XML documents that can trigger hash flooding attacks. Effective mitigation requires both updating the underlying libexpat library to version 2.8.0 or later and applying a corresponding patch to CPython. No official remediation level or patch links are provided in the available data.
