About Bleon-Ethical Api-Gateway-Deploy
CVE-2026-27208 affects Bleon-Ethical Api-Gateway-Deploy, a product from Bleon-Ethical. Before acting, confirm where Bleon-Ethical Api-Gateway-Deploy runs in your estate, who owns it and whether it is reachable from the internet, because exposure decides real risk more than the score alone.
What the flaw is
In plain terms: bleon-ethical/api-gateway-deploy provides API gateway deployment. Version 1.0.0 is vulnerable to an attack chain involving OS Command Injection and Privilege Escalation. This allows an attacker to execute arbitrary commands with root privileges within the container, potentially leading to a container escape and unauthorized infrastructure modifications. This is fixed in version 1.0.1 by implementing strict input sanitization and secure delimiters in entrypoint.sh, enforcing a non-root user (appuser) in the Dockerfile, and establishing mandatory security quality gates.
The weakness class is OS Command Injection. Untrusted input is passed to the operating system shell, letting an attacker run commands.
Based on its CVSS vector, the flaw needs local or adjacent access, needs no login, and needs no user interaction. Apply the vendor fix and confirm exposure on internet facing and business critical assets first.

How to detect it
- Inventory every instance of Bleon-Ethical Api-Gateway-Deploy and record the running version against the affected range above.
- Check external attack surface scans for internet facing instances of the component.
- Review logs on affected systems for unusual requests, errors or new processes around the vulnerable function.
- Confirm with an authenticated vulnerability scan once your scanner has a check for this CVE.
How to fix it
- Apply the fixed version of Bleon-Ethical Api-Gateway-Deploy named in the vendor advisory.
- If patching must wait, restrict network access to the affected service and put it behind authentication or a web application firewall rule.
- Rescan after the change to prove the exposure is gone, then close the ticket.

WeGIA is a web manager for charitable institutions. Prior to version 3.6.5, a critical Remote Code Execution (RCE) vulnerability exists in the WeGIA application's database restoration functionality. An attacker with administrative access (which can be obtained via the previously reported Authentication Bypass) can execute arbitrary OS commands on the server by uploading a backup file with a specifically crafted filename. Version 3.6.5 fixes the issue.
PDF Export Module used in DHTMLX's products Gantt and Scheduler is vulnerable to Remote Code Execution due to lack of "data" parameter sanitization. An unauthenticated attacker can inject the malicious JavaScript code to the parameter whose value is processed by Node.js and subsequently executed. This can lead to server compromise. This issue was fixed in PDF Export Module version 0.7.6.
TinyWeb is a web server (HTTP, HTTPS) written in Delphi for Win32. TinyWeb HTTP Server before version 1.98 is vulnerable to OS command injection via CGI ISINDEX-style query parameters. The query parameters are passed as command-line arguments to the CGI executable via Windows CreateProcess(). An unauthenticated remote attacker can execute arbitrary commands on the server by injecting Windows shell metacharacters into HTTP requests. This vulnerability is fixed in 1.98.
TinyWeb is a web server (HTTP, HTTPS) written in Delphi for Win32. A vulnerability in versions prior to 2.01 allows unauthenticated remote attackers to bypass the web server's CGI parameter security controls. Depending on the server configuration and the specific CGI executable in use, the impact is either source code disclosure or remote code execution (RCE). Anyone hosting CGI scripts (particularly interpreted languages like PHP) using vulnerable versions of TinyWeb is impacted. The problem has been patched in version 2.01. If upgrading is not immediately possible, ensure `STRICT_CGI_PARAMS` is enabled (it is defined by default in `define.inc`) and/or do not use CGI executables that natively accept dangerous command-line flags (such as `php-cgi.exe`). If hosting PHP, consider placing the server behind a Web Application Firewall (WAF) that explicitly blocks URL query string parameters that begin with a hyphen (`-`) or contain encoded double quotes (`%22`).
A command injection vulnerability exists in MLflow's model serving container initialization code, specifically in the `_install_model_dependencies_to_env()` function. When deploying a model with `env_manager=LOCAL`, MLflow reads dependency specifications from the model artifact's `python_env.yaml` file and directly interpolates them into a shell command without sanitization. This allows an attacker to supply a malicious model artifact and achieve arbitrary command execution on systems that deploy the model. The vulnerability affects versions 3.8.0 and is fixed in version 3.8.2.
