CVE-2026-7210 (GCVE-0-2026-7210)
Vulnerability from nvd – 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.

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.
