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-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::Content - HTTP 1.1 Content Base Class

SYNOPSIS

use Mojo::Base 'Mojo::Content';

DESCRIPTION

Mojo::Content is an abstract base class for HTTP 1.1 content as described in RFC 2616.

ATTRIBUTES

Mojo::Content implements the following attributes.

auto_relax

my $relax = $content->auto_relax;
$content  = $content->auto_relax(1);

Try to detect broken web servers and turn on relaxed parsing automatically.

headers

my $headers = $content->headers;
$content    = $content->headers(Mojo::Headers->new);

The headers.

on_read

my $cb   = $content->on_read;
$content = $content->on_read(sub {...});

Content parser callback.

$content = $content->on_read(sub {
  my ($self, $chunk) = @_;
  print $chunk;
});

relaxed

my $relaxed = $content->relaxed;
$content    = $content->relaxed(1);

Activate relaxed parsing for HTTP 0.9 and broken web servers.

METHODS

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

body_contains

my $found = $content->body_contains('foo bar baz');

Check if content contains a specific string.

body_size

my $size = $content->body_size;

Content size in bytes.

build_body

my $string = $content->build_body;

Render whole body.

build_headers

my $string = $content->build_headers;

Render all headers.

generate_body_chunk

my $chunk = $content->generate_body_chunk(0);

Generate dynamic content.

get_body_chunk

my $chunk = $content->get_body_chunk(0);

Get a chunk of content starting from a specfic position.

get_header_chunk

my $chunk = $content->get_header_chunk(13);

Get a chunk of the headers starting from a specfic position.

has_leftovers

my $leftovers = $content->has_leftovers;

Check if there are leftovers.

header_size

my $size = $content->header_size;

Size of headers in bytes.

is_chunked

my $chunked = $content->is_chunked;

Chunked transfer encoding.

is_done

my $done = $content->is_done;

Check if parser is done.

is_multipart

my $multipart = $content->is_multipart;

Multipart content.

is_parsing_body

my $body = $content->is_parsing_body;

Check if body parsing started yet.

leftovers

my $bytes = $content->leftovers;

Leftovers for next HTTP message.

parse

$content = $content->parse("Content-Length: 12\r\n\r\nHello World!");

Parse content.

parse_body

$content = $content->parse_body("Hi!");

Parse body.

parse_body_once

$content = $content->parse_body_once("Hi!");

Parse body once.

parse_until_body

$content = $content->parse_until_body(
  "Content-Length: 12\r\n\r\nHello World!"
);

Parse and stop after headers.

progress

my $bytes = $content->progress;

Number of bytes already received from message content. Note that this method is EXPERIMENTAL and might change without warning!

write

$content->write('Hello!');
$content->write('Hello!', sub {...});

Write dynamic content, the optional drain callback will be invoked once all data has been written.

write_chunk

$content->write_chunk('Hello!');
$content->write_chunk('Hello!', sub {...});

Write chunked content, the optional drain callback will be invoked once all data has been written.
