Missing Authorization vulnerability in jjlemstra Whydonate wp-whydonate allows Accessing Functionality Not Properly Constrained by ACLs.This issue affects Whydonate: from n/a through <= 4.0.15.
AnalysisAI
The Whydonate WordPress plugin through version 4.0.15 lacks proper authorization checks, enabling unauthenticated attackers to remotely access restricted functionality. This can lead to service disruption or resource exhaustion, with no data exposure or system compromise. No active exploitation is reported, but the public advisory confirms the flaw.
Technical ContextAI
This vulnerability is an instance of CWE-862 (Missing Authorization) in the Whydonate plugin, typically used for accepting donations on WordPress sites. The plugin fails to enforce access control lists (ACLs) on certain backend endpoints, allowing unauthenticated HTTP requests to reach administrative or privileged functions that should require authentication. The affected product is the jjlemstra/Whydonate plugin (Slug: wp-whydonate) as indicated by its CPE name.
Affected ProductsAI
The Whydonate plugin for WordPress (by jjlemstra) is affected from an unspecified starting version up to and including 4.0.15. The Patchstack advisory (https://patchstack.com/database/Wordpress/Plugin/wp-whydonate/vulnerability/wordpress-whydonate-plugin-4-0-15-broken-access-control-vulnerability?_s_id=cve) is the primary reference for affected version details.
RemediationAI
Upgrade the Whydonate plugin to a patched version beyond 4.0.15 once the vendor releases an official fix. Currently, no specific patched version number is provided in the advisory; monitor the vendor’s changelog or Patchstack for updates. As an immediate workaround, consider disabling the plugin if its donation functionality is not critical, or implement a web application firewall rule to block unauthorized access to the plugin’s REST endpoints (if known). Restricting external network access to the WordPress admin panel alone will not mitigate this issue, as exploitation may occur through public-facing endpoints.
