EIP tracks 1 public exploit for CVE-2026-48962. PoCs published by JoakimBulow.

AI-analyzed exploit summary The repository contains a functional exploit PoC for CVE-2026-48962, demonstrating an eval injection vulnerability in `File::GlobMapper::_getFiles()` that allows arbitrary Perl code execution via crafted fileglob arguments in `IO::Compress::*` functions.

Description

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.
