CVE-2025-30673Network attack vector

Code execution via current-directory module loading

Published Apr 1, 2025 · Updated Apr 1, 2025

Uncontrolled search path in Sub::HandlesVia before 0.050002 allows attackers to execute code via a malicious working-directory file. The Mite-generated code in lib/Sub/HandlesVia/Mite.pm adds the current directory to Perl's @INC search path, allowing an attacker-controlled module to replace the intended module. Exploitation requires placement of a matching file in the process's working directory; successful loading executes it with the process's privileges.
