Security Advisories (1)
CVE-2026-5083 (2026-04-08)

Ado::Sessions versions through 0.935 for Perl generates insecure session ids. The session id is generated from a SHA-1 hash seeded with the built-in rand function, the epoch time, and the PID. The PID will come from a small set of numbers, and the epoch time may be guessed, if it is not leaked from the HTTP Date header. The built-in rand function is unsuitable for cryptographic usage. Predicable session ids could allow an attacker to gain access to systems. Note that Ado is no longer maintained, and has been removed from the CPAN index. It is still available on BackPAN.

NAME

Ado::Manual::FiveMinutes - Start a personal blog in five minutes.

FIVE MINUTES

Within five minutes we will use Ado::Plugin::MarkdownRenderer and Ado::Control::Articles to create a personal blog.

Create a directory for Ado and install it in it.

mkdir ~/ado 
curl -L https://cpanmin.us | perl - -M https://cpan.metacpan.org -l ~/ado -n Ado

Start Ado in development mode.

cd ~/ado
morbo -w ./lib -w ./site_templates -w templates  bin/ado

You should see:

Server available at http://127.0.0.1:3000

Open a new terminal window and create a markdown file that will contain your first article. Or edit one of the already existing sample files there.

touch ~/ado/public/articles/my_article.md
vim ~/ado/public/articles/my_article.md

Eventually add a link to the newly created file (but with .html extension) to the menu containing links to the articles which are "published". Copy the menu template so it is not overwritten when you upgrade Ado.

mkdir -p ~/ado/site_templates/articles
cp ~/ado/templates/articles/menu.html.ep ~/ado/site_templates/articles/

#edit ~/ado/site_templates/articles/menu.html.ep

<a href="/articles/hello.html" class="item">История</a>
<a href="/articles/ala/bala.html" class="item">FooBar</a>
<!-- Add the next line to the templte. -->
<a href="/articles/my_article.html" class="item">My Article</a>

Go to http://127.0.0.1:3000/articles/my_article.html. Nice!

Enable caching of articles. The generated HTML will be stored as plain static files which will be served automatically on every next request.

touch ~/ado/etc/plugins/markdown_renderer.development.conf

Add the following code to markdown_renderer.development.conf:

{   
    #Do not convert files to HTML on every request
    #but reuse already produced html files.
    md_reuse_produced_html => 1,
};

Refresh http://127.0.0.1:3000/articles/my_article.html. In ~/ado/public/articles You will find my_article.html. Congratulations! You created your first article with Ado without much ado.

WHAT'S NEXT

Look at the source of Ado::Control::Articles to see how it works. Go to http://127.0.0.1:3000/ and play more or visit the links in the "SEE ALSO" section. Now you can fork the project on Github, improve menu.html.ep to automatically traverse the articles directory and generate the list of articles, then make a merge request. You just contributed to the project.
