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.
