CVE-2026-7210 end-of-life priority: Debian including 5 source packages (python2.7, python3.11, python3.13, python3.14, python3.9), 8 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): open 4, resolved 4.
`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.
