CVE-2024-9108
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 · uneditedThe Wechat Social login plugin for WordPress is vulnerable to arbitrary file uploads due to insufficient file type validation in the 'convert_remoteimage_to_local' function in versions up to, and including, 1.3.0. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible.
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.

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 if the Wechat Social login plugin is installedCheck the WordPress plugins directory (wp-content/plugins/) for a folder named 'wechat-social-login' or similar, and verify if the plugin appears in the WordPress admin under Plugins > Installed Plugins.Affected if The plugin folder exists in wp-content/plugins/ and the plugin is active in WordPress.

-
Locate the vulnerable function in the plugin codeSearch the plugin files for the string 'convert_remoteimage_to_local' using grep or a file search utility within the plugin directory.Affected if The function 'convert_remoteimage_to_local' exists in the plugin code, indicating the vulnerable feature is present.
-
Verify the remote image conversion feature is accessibleCheck the plugin settings or admin panel to determine if the remote image conversion functionality is enabled or exposed. Also examine the plugin's AJAX handlers or public endpoints that call the convert_remoteimage_to_local function.Affected if The remote image conversion feature is enabled or accessible without authentication.
If the Wechat Social login plugin is installed with version 1.3.0 or lower and the convert_remoteimage_to_local function is present and accessible, the environment is affected by CVE-2024-9108.
