Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Incorrect access control in the config.php component of Slah v1.5.0 and below allows unauthenticated attackers to access sensitive information, including active session credentials.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Slah v1.5.0 and below contains an incorrect access control vulnerability in the config.php component. The component allows unauthenticated attackers to directly access config.php and retrieve sensitive information, including active session credentials, without any authentication or authorization checks.

MitigationImplement proper authentication and authorization checks on the config.php component to ensure only authenticated users with appropriate privileges can access sensitive configuration files. Consider moving config.php outside the web root or adding .htaccess/deny rules.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Locate Slah installation
    Search the web root for files named config.php or directories containing Slah application files (controllers, models, views folders, etc.)
    Affected if Slah is installed on the system
  2. Determine installed Slah version
    Check version.php, composer.json, or any version file in the Slah installation directory; if unavailable, check the main index.php or a known changelog file for version markers
    Affected if Installed version is 1.5.0 or lower, or version cannot be determined and the file exists in an older installation
  3. Verify config.php exists in web-accessible location
    Locate config.php within the public web root (htdocs, public_html, or the main application directory served by the web server)
    Affected if config.php file exists in a web-accessible directory
  4. Test unauthenticated access to config.php
    Using a browser or curl command, attempt to access the config.php file directly via HTTP (e.g., curl -s http://TARGET_URL/config.php) without providing any authentication tokens or session cookies
    Affected if The file is served and returns HTTP 200 with content (not HTTP 403/401), indicating it is directly accessible without authentication
  5. Check for sensitive data exposure
    If config.php is accessible, inspect the response content for sensitive variables such as database credentials, API keys, session identifiers, or configuration arrays containing credentials
    Affected if The response contains unencrypted credentials, session tokens, database connection strings, or other sensitive configuration data

A Slah installation version 1.5.0 or below with config.php present in a web-accessible directory and directly retrievable via HTTP without authentication indicates the environment is affected by CVE-2026-30994.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
