CVE-2026-13048 (2026-08-13)

Data::MuForm::Localizer versions through 0.05 for Perl execute Perl from a message catalog header, reached at an arbitrary path because load_lexicon interpolates the language attribute into the catalog filename. load_lexicon builds the catalog path by appending `Messages/$lang.po` to the directory holding Localizer.pm, where $lang is the language attribute, with no check that it names a bare locale tag. A value holding `../` segments walks out of the message directory, so any readable path with a `.po` suffix is loaded. While parsing the catalog, extract_header_msgstr takes the `Plural-Forms:` header, prefixes `$` to the bare words nplurals, plural and n, and passes the rest verbatim into a string that is evaluated: the nplurals form evaluates the header expression immediately, and the plural_code form compiles it into a subroutine whose body runs when a plural message is localized. A header of `nplurals=2; plural=(system('...'),0);` therefore runs that command as the catalog loads. The evaluation inherits strict, so an expression that assigns to an undeclared variable fails to compile, while one built from calls alone does not. An application that sets the language attribute from request data, an Accept-Language header or a locale parameter, and an attacker who can place a file with a `.po` suffix and chosen contents at a readable path, together give code execution as the application user. The message expansion path is not affected: expand_named substitutes only the placeholder names the caller supplies, and _mangle_value returns the value unchanged.

NAME

StarterView::Form::Jobs::KeywordLocationSearch

SYNOPSIS

Job seeker search form with keyword (job title) and location fields. This form
also supports sticky search filters when paired with
L<StarterView::Form::Jobs::SearchFilter>.

FIELDS

job_search_id

The (encrypted) id of the search for searches that have been saved.
Job title or keyword text field. Either this field or the location
field is required.

location

Location text field. Either this field or the search field is required.

radius

This field makes the current search radius filter sticky.

This field is inactive by default, and can be activated by including the field
name in the list of C<active> fields passed to C<process>.

days

This field makes the current search posted date filter sticky.

RENDERING

build_render_list

This function builds the list of fields that should be rendered in the form.
For the search form these are the two visible fields, the submit button and
any (sticky) hidden fields that have a value.

The list of hidden fields with a value is obtained through the
L<StarterView::Form::Role::RenderHiddenFields> role.

VALIDATION

validate

Form level validation. This form requires at least the search field or the
location field.

validate_radius

Radius filter field validation. The radius filter value must be a positive
numeric value.

validate_days

Post date filter field validation. The post date filter value must be a
positive integer value.
