It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1954 advisory.

    When using the configparser module to write configuration filescontaining multi-line text values with     carriage return characters (\r) theresulting file could be injected with unexpected keys and values if     theattacker controls the written value. (CVE-2026-0864)

    When using the tarfile module with a file opened in streaming mode (mode=r|) the tarfile module did     not properly handle EOF, making archive parsing take exponentially longer. (CVE-2026-11972)

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

    unicodedata.normalize() can take excessive CPU time when processing specially crafted Unicode input     containing long runs of combining characters with alternating Canonical Combining Class values. This     affects all normalization forms. (CVE-2026-3276)

    tarfile.data_filter could be bypassed using crafted link entries, including symlinks with empty or     directory-like names, to redirect later archive members outside the intended extraction directory. This     allowed a malicious tar archive to cause tarfile.extractall() to write files outside the destination     directory, subject to the permissions of the extracting process. (CVE-2026-7774)

    bz2.BZ2Decompressor objects could be reused after a decompression error. If an application caught the     resulting OSError and retried with the same decompressor, crafted input could cause the decompressor to     resume from an invalid internal state and perform out-of-bounds writes to a stack buffer. This could crash     the process when processing untrusted data. (CVE-2026-9669)

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

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
