It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1825 advisory.

    IO::Uncompress::Unzip versions before 2.220 for Perl allow CPU exhaustion via per-byte read loop in     fastForward.

    fastForward() compares length $offset (the digit count of the offset, 1 to 19) against the chunk size $c     instead of $offset itself, so $c shrinks from 16 KiB to 1-19 bytes per iteration.

    Extracting a named entry from an attacker supplied zip via IO::Uncompress::Unzip->new($zip, Name =>     $target) drives a per-byte read loop scaling with the entry's compressed size, up to the non-Zip64 4 GiB     cap. (CVE-2026-48959)

    IO::Compress versions from 2.207 before 2.220 for Perl ship a zipdetails CLI tool that crashes with     undefined subroutine on Info-ZIP Unix Extra Field with 8-byte UID or GID.

    When decode_ux() in bin/zipdetails handles an Info-ZIP Unix Extra Field (tag 0x7875) with UID Size or GID     Size set to 8, causing zipdetails to decode an 8-byte UID or GID value, it dispatches through     decodeLitteEndian(), which calls a misnamed helper unpackValueQ. The actual function defined in the same     file is unpackValue_Q (with underscore); the call raises 'Undefined subroutine &main::unpackValueQ' and     the script exits with status 255.

    Library callers of IO::Compress and IO::Uncompress are not affected; the defect is in the bundled CLI     tool. (CVE-2026-48961)

    IO::Compress versions before 2.220 for Perl can execute arbitrary code in File::GlobMapper via an     attacker-controlled output glob.

    _parseOutputGlob() wraps the caller-supplied output glob string in double quotes and stores it in the     parser state; _getFiles() then runs the stored expression through eval STRING. A literal double quote in     the output glob closes the dquote wrapper, and the characters that follow are evaluated as Perl.

    Arbitrary Perl in the output glob executes at the calling process's privilege. (CVE-2026-48962)
