CVE-2021-3129
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 · uneditedIgnition before 2.5.2, as used in Laravel and other products, allows unauthenticated remote attackers to execute arbitrary code because of insecure usage of file_get_contents() and file_put_contents(). This is exploitable on sites using debug mode with Laravel before 8.4.2.
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 confidenceIgnition before 2.5.2 contains insecure usage of file_get_contents() and file_put_contents() that allows unauthenticated remote attackers to write arbitrary PHP code to server files, leading to remote code execution. The vulnerability is exploitable on Laravel deployments using debug mode.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify installed Ignition versionCheck the composer.json file in your Laravel project root, look for 'facade/ignition' in the require section, or inspect vendor/composer/installed.json to find the installed versionAffected if The installed version is less than 2.5.2 (e.g., 2.5.1, 2.5.0, 2.4.x, etc.)
-
Locate Laravel configuration fileFind the .env file in your Laravel project root (or .env.example if .env is missing)Affected if The .env file exists in the project
-
Check if debug mode is enabledIn the .env file, look for the APP_DEBUG settingAffected if APP_DEBUG is set to true (or APP_DEBUG is missing and defaults to true in config/app.php)
You are affected if your installed Ignition version is below 2.5.2 AND Laravel debug mode (APP_DEBUG=true) is enabled in your environment.
Generated from the published advisory. Verify against your own configuration.
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.
dbcve · scoped2.5.2
Upgrade Ignition to 2.5.2 or later (and Laravel to 8.4.2+ if applicable), and ensure debug mode is disabled in production environments.
Ignition >= 2.5.2 or Laravel >= 8.4.2
- Upgrade Ignition to version 2.5.2 or later. For Laravel users, update the ignition package via composer: 'composer require ignition/ignition:^2.5.2' or update Laravel to version 8.4.2 or later which includes the fixed Ignition dependency.
