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.

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

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;

DESCRIPTION

Mojo::ByteStream provides a more friendly API for the bytestream manipulation functions in Mojo::Util.

METHODS

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

new

my $stream = Mojo::ByteStream->new('test123');

Construct a new Mojo::ByteStream object.

b64_decode

$stream = $stream->b64_decode;

Base64 decode bytestream.

b64_encode

$stream = $stream->b64_encode;
$stream = $stream->b64_encode('');

Base64 encode bytestream.

camelize

$stream = $stream->camelize;

Convert snake case bytestream to camel case and replace - with ::.

foo_bar     -> FooBar
foo_bar-baz -> FooBar::Baz

clone

my $stream2 = $stream->clone;

Clone bytestream.

decamelize

$stream = $stream->decamelize;

Convert camel case bytestream to snake case and replace :: with -.

FooBar      -> foo_bar
FooBar::Baz -> foo_bar-baz

decode

$stream = $stream->decode;
$stream = $stream->decode($encoding);

Decode bytestream, defaults to UTF-8.

$stream->decode('UTF-8')->to_string;

encode

$stream = $stream->encode;
$stream = $stream->encode($encoding);

Encode bytestream, defaults to UTF-8.

$stream->encode('UTF-8')->to_string;

hmac_md5_sum

$stream = $stream->hmac_md5_sum($secret);

Turn bytestream into HMAC-MD5 checksum of old content.

hmac_sha1_sum

$stream = $stream->hmac_sha1_sum($secret);

Turn bytestream into HMAC-SHA1 checksum of old content.

html_escape

$stream = $stream->html_escape;

HTML escape bytestream.

html_unescape

$stream = $stream->html_unescape;

HTML unescape bytestream.

md5_bytes

$stream = $stream->md5_bytes;

Turn bytestream into binary MD5 checksum of old content.

md5_sum

$stream = $stream->md5_sum;

Turn bytestream into MD5 checksum of old content.

punycode_decode

$stream = $stream->punycode_decode;

Punycode decode bytestream.

punycode_encode

$stream = $stream->punycode_encode;

Punycode encode bytestream.

qp_decode

$stream = $stream->qp_decode;

Quoted Printable decode bytestream.

qp_encode

$stream = $stream->qp_encode;

Quoted Printable encode bytestream.

quote

$stream = $stream->quote;

Quote bytestream.

say

$stream->say;
$stream->say(*STDERR);

Print bytestream to handle or STDOUT and append a newline.

secure_compare

my $success = $stream->secure_compare($string);

Constant time comparison algorithm to prevent timing attacks.

sha1_bytes

$stream = $stream->sha1_bytes;

Turn bytestream into binary SHA1 checksum of old content.

sha1_sum

$stream = $stream->sha1_sum;

Turn bytestream into SHA1 checksum of old content.

size

my $size = $stream->size;

Size of bytestream.

split

my $collection = $stream->split(',');

Turn bytestream into Mojo::Collection. Note that this method is EXPERIMENTAL and might change without warning!

$stream->split(',')->map(sub { $_->quote })->join("\n")->say;

to_string

my $string = $stream->to_string;

Stringify bytestream.

trim

$stream = $stream->trim;

Trim whitespace characters from both ends of bytestream.

unquote

$stream = $stream->unquote;

Unquote bytestream.

url_escape

$stream = $stream->url_escape;
$stream = $stream->url_escape('A-Za-z0-9\-\.\_\~');

URL escape bytestream.

url_unescape

$stream = $stream->url_unescape;

URL unescape bytestream.

xml_escape

$stream = $stream->xml_escape;

XML escape bytestream, this is a much faster version of html_escape escaping only the characters &, <, >, " and '.
