Security Advisories (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.

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.

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.

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.

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.

NAME

Mojo::Cookie::Response - HTTP response cookie

SYNOPSIS

use Mojo::Cookie::Response;

my $cookie = Mojo::Cookie::Response->new;
$cookie->name('foo');
$cookie->value('bar');
say "$cookie";

DESCRIPTION

Mojo::Cookie::Response is a container for HTTP response cookies, based on RFC 6265.

ATTRIBUTES

Mojo::Cookie::Response inherits all attributes from Mojo::Cookie and implements the following new ones.

domain

my $domain = $cookie->domain;
$cookie    = $cookie->domain('localhost');

Cookie domain.

expires

my $expires = $cookie->expires;
$cookie     = $cookie->expires(time + 60);

Expiration for cookie.

httponly

my $bool = $cookie->httponly;
$cookie  = $cookie->httponly($bool);

HttpOnly flag, which can prevent client-side scripts from accessing this cookie.

max_age

my $max_age = $cookie->max_age;
$cookie     = $cookie->max_age(60);

Max age for cookie.

origin

my $origin = $cookie->origin;
$cookie    = $cookie->origin('mojolicious.org');

Origin of the cookie.

path

my $path = $cookie->path;
$cookie  = $cookie->path('/test');

Cookie path.

secure

my $bool = $cookie->secure;
$cookie  = $cookie->secure($bool);

Secure flag, which instructs browsers to only send this cookie over HTTPS connections.

METHODS

Mojo::Cookie::Response inherits all methods from Mojo::Cookie and implements the following new ones.

parse

my $cookies = Mojo::Cookie::Response->parse('f=b; path=/');

Parse cookies.

to_string

my $str = $cookie->to_string;

Render cookie.
