CVE-2026-15747 (2026-07-14)

Mojolicious versions from 4.59 before 9.48 for Perl expose a stable representation of the session CSRF token to a BREACH compression oracle. _csrf_token generates and caches one token per session and returns the same value on every call, and _csrf_field places that value in a hidden `csrf_token` input. When a response carrying the token also echoes attacker-controlled input and is gzip-compressed, the chosen values and the resulting compressed lengths form a BREACH oracle. An attacker able to query it can recover the token and pass csrf_protect validation.

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

Mojolicious::Routes::Match - Find routes

SYNOPSIS

use Mojolicious::Controller;
use Mojolicious::Routes;
use Mojolicious::Routes::Match;

# Routes
my $r = Mojolicious::Routes->new;
$r->get('/user/:id');
$r->put('/user/:id');

# Match
my $c = Mojolicious::Controller->new;
my $match = Mojolicious::Routes::Match->new(root => $r);
$match->find($c => {method => 'PUT', path => '/user/23'});
say $match->stack->[0]{id};

# Render
say $match->path_for->{path};
say $match->path_for(id => 24)->{path};

DESCRIPTION

Mojolicious::Routes::Match finds routes in Mojolicious::Routes structures.

ATTRIBUTES

Mojolicious::Routes::Match implements the following attributes.

endpoint

my $route = $match->endpoint;
$match    = $match->endpoint(Mojolicious::Routes::Route->new);

The route endpoint that matched, usually a Mojolicious::Routes::Route object.

position

my $position = $match->position;
$match       = $match->position(2);

Current position on the "stack", defaults to 0.

root

my $root = $match->root;
$match   = $match->root(Mojolicious::Routes->new);

The root of the route structure, usually a Mojolicious::Routes object.

stack

my $stack = $match->stack;
$match    = $match->stack([{action => 'foo'}, {action => 'bar'}]);

Captured parameters with nesting history.

METHODS

Mojolicious::Routes::Match inherits all methods from Mojo::Base and implements the following new ones.

find

$match->find(Mojolicious::Controller->new, {method => 'GET', path => '/'});

Match controller and options against "root" to find an appropriate "endpoint".

path_for

my $info = $match->path_for;
my $info = $match->path_for(foo => 'bar');
my $info = $match->path_for({foo => 'bar'});
my $info = $match->path_for('named');
my $info = $match->path_for('named', foo => 'bar');
my $info = $match->path_for('named', {foo => 'bar'});

Render matching route with parameters into path.
