CVE-2026-48962— IO::Compress versions before 2.220 for Perl can execute arbitrary code in File::GlobMapper via an attacker-controlled output glob

Quick assessment

Affected
PMQS IO::Compress
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

IO-Compress是Paul Marquess个人开发者的一个支持多种压缩格式的Perl读写接口库。 IO-Compress 2.220之前版本存在安全漏洞，该漏洞源于File::GlobMapper中通过攻击者控制的输出glob执行任意代码，_parseOutputGlob将输出glob字符串包裹在双引号中并存储，_getFiles通过eval STRING执行存储的表达式，输出glob中的双引号关闭包裹器后后续字符被评估为Perl，任意Perl代码以调用进程权限执行。

Vulnerability Title
IO::Compress versions before 2.220 for Perl can execute arbitrary code in File::GlobMapper via an attacker-controlled output glob
Source: CVE Program / CVE List V5
Vulnerability 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.
