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
WeGIA is a web manager for charitable institutions. Prior to version 3.6.5, an unsafe use of the `extract()` function on the `$_REQUEST` superglobal allows an unauthenticated attacker to overwrite local variables in multiple PHP scripts. This vulnerability can be leveraged to completely bypass authentication checks, allowing unauthorized access to administrative and protected areas of the WeGIA application. Version 3.6.5 fixes the issue.

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

WeGIA uses the PHP extract() function unsafely on the $_REQUEST superglobal in multiple scripts. This imports request parameters directly into the local variable scope, allowing attackers to overwrite application variables including those controlling authentication state. By supplying specific variable names as request parameters, unauthenticated users can bypass login checks and access administrative functions.

MitigationUpgrade WeGIA to version 3.6.5 or later, which replaces the unsafe extract() usage with secure input handling. If immediate upgrade is not possible, audit all PHP files using extract() on superglobals and replace with explicit variable assignment or filter_input().

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. Identify WeGia version
    Locate the version file or check the version identifier in the WeGia installation. Common locations include a version.php file, config file, or the administrative interface About page.
    Affected if The installed version is less than 3.6.5
  2. Search for unsafe extract() usage on superglobals
    Search the WeGia PHP source files for patterns: extract($_REQUEST), extract($_GET), extract($_POST), or extract($_SERVER). Use grep or a file search tool across the web root directory.
    Affected if Any PHP file contains extract() called directly on superglobals without the EXTR_SKIP or EXTR_PREFIX_ALL flags
  3. Identify variable overwrite potential
    Examine the extracted variables in context. Look for authentication-related variables such as $login, $authenticated, $user, $is_admin, or session variables that control access. Check if these can be supplied as HTTP request parameters.
    Affected if Variables controlling authentication state or session can be overwritten via request parameters
  4. Verify application accessibility
    Confirm the WeGia application is accessible over HTTP/HTTPS and the login/management interface is reachable.
    Affected if The WeGia web interface is exposed and accepts user requests containing arbitrary parameter names

A user is affected if WeGia version is below 3.6.5 AND the codebase contains extract() applied to $_REQUEST or other superglobals without proper sanitization, allowing authentication bypass via parameter injection.

dbcve · scoped
Upgrade available Upgrade to 3.6.5 or later
Fixed in 3.6.5
Interim mitigation

Upgrade WeGIA to version 3.6.5 or later, which replaces the unsafe extract() usage with secure input handling. If immediate upgrade is not possible, audit all PHP files using extract() on superglobals and replace with explicit variable assignment or filter_input().

Recommended fix High confidence

WeGIA version 3.6.5

  1. 1. Back up the current WeGIA installation including all files and the database
  2. 2. Download WeGIA version 3.6.5 from the official GitHub repository (github.com)
  3. 3. Replace all existing WeGIA PHP files with the new version 3.6.5 files
  4. 4. Verify the extract() function is no longer used unsafely on $_REQUEST superglobal in the new version
  5. 5. Test that authentication and authorization mechanisms function correctly after upgrade
  6. 6. Verify the application functions normally with standard workflows
