Detailsinfo

A vulnerability was found in PMQS IO::Compress up to 2.219 on Perl. It has been classified as critical. Affected is the function _parseOutputGlob. The manipulation with an unknown input leads to a eval injection vulnerability. CWE is classifying the issue as CWE-95. The product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes code syntax before using the input in a dynamic evaluation call (e.g. "eval"). This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

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.

The advisory is shared for download at github.com. This vulnerability is traded as CVE-2026-48962 since 05/26/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. There are known technical details, but no exploit is available.
