CVE-2025-40909 (2025-05-30)

Perl threads have a working directory race condition where file operations may target unintended paths. If a directory handle is open at thread creation, the process-wide current working directory is temporarily changed in order to clone that handle for the new thread, which is visible from any third (or more) thread already running. This may lead to unintended operations such as loading code or accessing files from unexpected locations, which a local attacker may be able to exploit. The bug was introduced in commit 11a11ecf4bea72b17d250cfb43c897be1341861e and released in Perl version 5.13.6

NAME

Test2::Tools::Exports - Tools for validating exporters.

DESCRIPTION

These are tools for checking that symbols have been imported into your namespace.

SYNOPSIS

use Test2::Tools::Exports

use Data::Dumper;
imported_ok qw/Dumper/;
not_imported_ok qw/dumper/;

EXPORTS

All subs are exported by default.

imported_ok(@SYMBOLS)

Check that the specified symbols exist in the current package. This will not find inherited subs. This will only find symbols in the current package's symbol table. This WILL NOT confirm that the symbols were defined outside of the package itself.

imported_ok( '$scalar', '@array', '%hash', '&sub', 'also_a_sub' );

@SYMBOLS can contain any number of symbols. Each item in the array must be a string. The string should be the name of a symbol. If a sigil is present then it will search for that specified type, if no sigil is specified it will be used as a sub name.

not_imported_ok(@SYMBOLS)

Check that the specified symbols do not exist in the current package. This will not find inherited subs. This will only look at symbols in the current package's symbol table.

not_imported_ok( '$scalar', '@array', '%hash', '&sub', 'also_a_sub' );

@SYMBOLS can contain any number of symbols. Each item in the array must be a string. The string should be the name of a symbol. If a sigil is present, then it will search for that specified type. If no sigil is specified, it will be used as a sub name.

CAVEATS

Before Perl 5.10, it is very difficult to distinguish between a package scalar that is undeclared vs declared and undefined. Currently imported_ok and not_imported_ok cannot see package scalars declared using our $var unless the variable has been assigned a defined value.

This will pass on recent perls, but fail on perls older than 5.10:

use Test2::Tools::Exports;

our $foo;

# Fails on perl onlder than 5.10
imported_ok(qw/$foo/);

If $foo is imported from another module, or imported using use vars qw/$foo/; then it will work on all supported perl versions.

use Test2::Tools::Exports;

use vars qw/$foo/;
use Some::Module qw/$bar/;

# Always works
imported_ok(qw/$foo $bar/);
