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.

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

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

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

Mojo::ByteStream - ByteStream

SYNOPSIS

# Manipulate bytestreams
use Mojo::ByteStream;
my $stream = Mojo::ByteStream->new('foo_bar_baz');
say $stream->camelize;

# Chain methods
my $stream = Mojo::ByteStream->new('foo bar baz')->quote;
$stream = $stream->unquote->encode('UTF-8')->b64_encode('');
say $stream;

# Use the alternative constructor
use Mojo::ByteStream 'b';
my $stream = b('foobarbaz')->html_escape;
