CVE-2026-7210 (GCVE-0-2026-7210)
Vulnerability from cvelistv5 – Published: 2026-05-11 17:19 – Updated: 2026-06-10 18:57
VLAI
Title
The expat and elementtree parsers use insufficient entropy for XML hash-flooding protection
Summary
`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.
