CPANSA-Mojolicious-2022-03 (2022-12-10)

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

CPANSA-Mojolicious-2021-02 (2021-06-01)

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.

CPANSA-Mojolicious-2018-03 (2018-05-19)

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

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

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

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

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

CPANSA-Mojolicious-2015-01 (2015-02-02)

Directory traversal on Windows

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

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

CVE-2011-1589 (2011-04-05)

Directory traversal vulnerability in Path.pm in Mojolicious before 1.16 allows remote attackers to read arbitrary files via a %2f..%2f (encoded slash dot dot slash) in a URI.

CVE-2010-4803 (2011-05-03)

Mojolicious before 0.999927 does not properly implement HMAC-MD5 checksums, which has unspecified impact and remote attack vectors.

CVE-2010-4802 (2011-05-03)

Commands.pm in Mojolicious before 0.999928 does not properly perform CGI environment detection, which has unspecified impact and remote attack vectors.

CVE-2011-1841 (2011-03-10)

Cross-site scripting (XSS) vulnerability in the link_to helper in Mojolicious before 1.12 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.

CVE-2026-14803 (2026-07-06)

Mojo::JSON versions before 9.47 for Perl allow memory exhaustion via unbounded recursion in the pure-Perl decoder. The pure-Perl decode path (`_decode_value` dispatching to `_decode_array` and `_decode_object`) recurses with no depth limit, so a small deeply nested JSON document can consume excessive memory. This path is the default when Cpanel::JSON::XS is not installed or `MOJO_NO_JSON_XS=1` is set; the Cpanel::JSON::XS fast path is not affected. Any caller that decodes an untrusted JSON body, for example `Mojo::Message::json` reached through `$c->req->json`, can exhaust process memory and cause denial of service.

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 an HMAC session cookie secret by default. These predictable default secrets can be exploited by an attacker 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

Mojo::Stateful - Stateful Base Class

SYNOPSIS

use base 'Mojo::Stateful';

DESCRIPTION

Mojo::Stateful is an abstract base class for state keeping objects.

ATTRIBUTES

Mojo::Stateful implements the following attributes.

state_cb

my $cb    = $stateful->state_cb;
$stateful = $stateful->state_cb(sub {...});

Callback that will be invoked whenever the state of this object changes.

METHODS

Mojo::Stateful inherits all methods from Mojo::Base and implements the following new ones.

done

$stateful = $stateful->done;

Shortcut for setting the current state to done.

error

my $error = $stateful->error;
$stateful = $stateful->error(500);

Shortcut for setting the current state to error.

has_error

my $has_error = $stateful->has_error;

Check if an error occured.

is_done

my $done = $stateful->is_done;

Check if the state machine is done.

is_finished

my $finished = $stateful->is_finished;

Check if the state machine is finished, this includes the states done, done_with_leftovers and error.

is_state

my $is_state = $stateful->is_state('writing');
my $is_state = $stateful->is_state(qw/error reading writing/);

Check if the state machine is currently in a specific state.

state

my $state = $stateful->state;
$stateful = $stateful->state('writing');

The current state.
