    CVE-2026-56412 (GCVE-0-2026-56412)

    Vulnerability from nvd – Published: 2026-06-21 15:58 – Updated: 2026-06-22 16:31
    VLAI
    Summary
    libexpat before 2.8.2 does not consider XML_TOK_DATA_CHARS in doCdataSection and thus lacks handler call depth tracking for various calls from within handlers in cases of a policy violation. Thus, a use-after-free can occur. NOTE: this issue exists because of an incomplete fix for CVE-2026-50219.

    CVE-2026-7210 (GCVE-0-2026-7210)

    Vulnerability from nvd – Published: 2026-05-11 17:19 – Updated: 2026-06-10 18:57

    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.

    CVE-2026-56412 (GCVE-0-2026-56412)

    Vulnerability from cvelistv5 – Published: 2026-06-21 15:58 – Updated: 2026-06-22 16:31
    VLAI
    Summary
    libexpat before 2.8.2 does not consider XML_TOK_DATA_CHARS in doCdataSection and thus lacks handler call depth tracking for various calls from within handlers in cases of a policy violation. Thus, a use-after-free can occur. NOTE: this issue exists because of an incomplete fix for CVE-2026-50219.
    Severity
    4.9 (Medium)

    CVE-2026-56131 (GCVE-0-2026-56131)

    Vulnerability from cvelistv5 – Published: 2026-06-19 02:56 – Updated: 2026-06-22 14:58
    VLAI
    Summary
    libexpat before 2.8.2 lacks handler call depth tracking for calls to XML_ResumeParser from within handlers in cases of a policy violation. Thus, a use-after-free can occur (similar to the CVE-2026-50219 situation).

    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.
