Mojo::DOM did not correctly parse <script> tags.

Small sessions could be used as part of a brute-force attack to decode the session secret.

CVE-2021-47208 (2021-03-16)

A bug in format detection can potentially be exploited for a DoS attack.

CVE-2018-25100 (2018-02-13)

Mojo::UserAgent::CookieJar leaks old cookies because of the missing host_only flag on empty domain.

Directory traversal on Windows

Mojo::UserAgent was not checking peer SSL certificates by default.

CVE-2020-36829 (2020-11-10)

Mojo::Util secure_compare can leak the string length. By immediately returning when the two strings are not the same length, the function allows an attacker to guess the length of the secret string using timing attacks.

CPANSA-Mojolicious-2018-02 (2018-05-11)

GET requests with embedded backslashes can be used to access local files on Windows hosts

CPANSA-Mojolicious-2014-01 (2014-10-07)

Context sensitivity of method param could lead to parameter injection attacks.

CVE-2024-58134 (2025-05-03)

Mojolicious versions from 0.999922 for Perl uses a hard coded string, or the application's class name, as a HMAC session secret by default. These predictable default secrets can be exploited to forge session cookies. An attacker who knows or guesses the secret could compute valid HMAC signatures for the session cookie, allowing them to tamper with or hijack another user's session.

NAME

Mojolicious::Validator::Validation - Perform validations

SYNOPSIS

use Mojolicious::Validator;
use Mojolicious::Validator::Validation;

my $validator = Mojolicious::Validator->new;
my $validation
  = Mojolicious::Validator::Validation->new(validator => $validator);
$validation->input({foo => 'bar'});
$validation->required('foo')->in(qw(bar baz));
say $validation->param('foo');

DESCRIPTION

Mojolicious::Validator::Validation performs Mojolicious::Validator validation checks.

ATTRIBUTES

Mojolicious::Validator::Validation implements the following attributes.

csrf_token

my $token   = $validation->token;
$validation = $validation->token('fa6a08...');

CSRF token.

input

my $input   = $validation->input;
$validation = $validation->input({foo => 'bar', baz => [123, 'yada']});

Data to be validated.

output

my $output  = $validation->output;
$validation = $validation->output({});

Validated data.

topic

my $topic   = $validation->topic;
$validation = $validation->topic('foo');

Name of field currently being validated.

validator

my $validator = $validation->validator;
$validation   = $validation->validator(Mojolicious::Validator->new);

Mojolicious::Validator object this validation belongs to.

METHODS

Mojolicious::Validator::Validation inherits all methods from Mojo::Base and implements the following new ones.

check

$validation = $validation->check('size', 2, 7);

Perform validation check on all values of the current "topic", no more checks will be performed on them after the first one failed.

csrf_protect

$validation = $validation->csrf_protect;

Validate csrf_token and protect from cross-site request forgery.

error

my @names   = $validation->error;
my $err     = $validation->error('foo');
$validation = $validation->error(foo => ['custom_check']);

Get or set details for failed validation check, at any given time there can only be one per field.

my ($check, $result, @args) = @{$validation->error('foo')};

has_data

my $bool = $validation->has_data;

Check if "input" is available for validation.

has_error

my $bool = $validation->has_error;
my $bool = $validation->has_error('foo');

Check if validation resulted in errors, defaults to checking all fields.

is_valid

my $bool = $validation->is_valid;
my $bool = $validation->is_valid('foo');

Check if validation was successful and field has a value, defaults to checking the current "topic".

optional

$validation = $validation->optional('foo');

Change validation "topic".

param

my @names       = $validation->param;
my $foo         = $validation->param('foo');
my @foo         = $validation->param('foo');
my ($foo, $bar) = $validation->param(['foo', 'bar']);

Access validated parameters, similar to "param" in Mojolicious::Controller.

required

$validation = $validation->required('foo');

Change validation "topic" and make sure a value is present and not an empty string.

AUTOLOAD

In addition to the "ATTRIBUTES" and "METHODS" above, you can also call validation checks provided by "validator" on Mojolicious::Validator::Validation objects, similar to "check".

$validation->required('foo')->size(2, 5)->like(qr/^[A-Z]/);
$validation->optional('bar')->equal_to('foo');
$validation->optional('baz')->in(qw(test 123));
