"It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1774 advisory.

    The tarfile module would still apply normalization of AREGTYPE (\x00) blocks to DIRTYPE, even while
    processing a multi-block member such as GNUTYPE_LONGNAME or GNUTYPE_LONGLINK. This could result in a
    crafted tar archive being misinterpreted by the tarfile module compared to other implementations.
    (CVE-2025-13462)

    CR/LF bytes were not rejected by HTTP client proxy tunnel headers or host. (CVE-2026-1502)

    The profiling.sampling module (Python 3.15+) and asyncio introspection capabilities (3.14+, python -m
    asyncio ps and python -m asyncio pstree) features could be used to read and write addresses in a
    privileged process if that process connected to a malicious or infected Python process via the remote
    debugging feature. This vulnerability requires persistently and repeatedly connecting to the process to be
    exploited, even after the connecting process crashes with high likelihood due to ASLR. (CVE-2026-5713)

    http.cookies.Morsel.js_output() returns an inline <script> snippet and only escapes  for JavaScript
    string context. It does not neutralize the HTML parser-sensitive sequence </script> inside the generated
    script element. Mitigation base64-encodes the cookie value to disallow escaping using cookie value.
    (CVE-2026-6019)

    `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-2026-7210)

Tenable has extracted the preceding description block directly from the tested product security advisory.
