CVE-2025-49910
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 · uneditedMissing Authorization vulnerability in AmentoTech Private Limited WPGuppy wpguppy-lite allows Accessing Functionality Not Properly Constrained by ACLs.This issue affects WPGuppy: from n/a through <= 1.1.4.
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 confidenceMissing Authorization vulnerability in the WPGuppy WordPress plugin allows unauthenticated or unauthorized users to access functionality that should be protected by Access Control Lists (ACLs). The plugin fails to properly enforce permission checks on certain functions, enabling attackers to potentially perform actions outside their intended privileges.

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.
-
Verify WPGuppy plugin installationNavigate to WordPress admin > Plugins and locate WPGuppy, or check the /wp-content/plugins/ directory for the wpguppy folder and read the main plugin file to identify the installed version numberAffected if WPGuppy plugin is installed and the version matches or precedes the patched version (if known)
-
Identify sensitive function exposureReview plugin source code in /wp-content/plugins/wpguppy/ for functions that handle user data, settings, or privileged operations. Check if these functions are hooked to WordPress AJAX actions (wp_ajax_) or REST API endpoints without capability checks like current_user_can()Affected if Sensitive functions are hooked to public or authenticated-but-unauthorized endpoints without permission verification
-
Check AJAX and REST API hooksSearch plugin files for add_action('wp_ajax_...') and add_action('wp_ajax_nopriv_...') calls. Also check register_rest_route() calls. Examine whether these hooks verify user capabilities before executingAffected if The plugin registers AJAX or REST endpoints accessible to unauthenticated users (wp_ajax_nopriv_) or any logged-in user without role verification
-
Inspect ACL configurationCheck plugin settings pages in WordPress admin for Access Control List configurations. Look for any settings that control which user roles can access specific plugin features. Verify if these settings are properly enforced in the codeAffected if ACL settings exist but are not properly enforced or can be bypassed in the plugin code
A user is affected if the WPGuppy plugin is installed and sensitive functions lack proper capability checks (current_user_can) or are accessible without authentication or authorization validation.

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.
From vendor dataImplement proper authorization checks (such as current_user_can() capability checks) on all sensitive functions and verify user roles/permissions before executing privileged operations. Update to a patched version if available.
