Hi,

The following vulnerability was published for libio-compress-perl.

CVE-2026-48962[0]:
| 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.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
