CVE-2025-67583: 
WordPress vulnerability analysis and mitigation

CVE-2025-67583 is a Missing Authorization vulnerability in the IDonate WordPress plugin developed by ThemeAtelier (formerly attributed to Foysal Imran). It allows unauthenticated remote attackers to exploit incorrectly configured access control security levels. All versions of the IDonate plugin through 2.1.15 are affected; version 2.1.16 addresses the issue. The vulnerability was published on December 9, 2025, and carries a CVSS v3.1 base score of 5.3 (Medium) (Feedly, Patchstack).

The root cause is classified as CWE-862 (Missing Authorization), meaning the plugin fails to properly verify whether a requesting user has the necessary permissions before executing certain actions or exposing functionality. The attack vector is network-based, requires no authentication, no user interaction, and low attack complexity, making it trivially exploitable by any remote attacker. The specific plugin functions or endpoints lacking authorization checks have not been publicly detailed in available sources, but the vulnerability class typically involves unprotected AJAX handlers or REST API endpoints in WordPress plugins (Feedly, Patchstack).

Successful exploitation results in a low integrity impact with no confidentiality or availability impact, per the CVSS scoring. An unauthenticated attacker could perform unauthorized actions within the IDonate plugin — such as modifying donation-related data or plugin settings — without valid credentials. The scope is limited to the affected WordPress installation and does not directly enable lateral movement or sensitive data exfiltration based on available information (Feedly).

No public proof-of-concept exploit code or evidence of in-the-wild exploitation has been reported for CVE-2025-67583. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. The EPSS score is approximately 0.028%, indicating a very low probability of exploitation in the near term (Feedly).

Users should update the IDonate WordPress plugin to version 2.1.16 or later, which resolves the missing authorization issue. As a general workaround prior to patching, site administrators can temporarily deactivate the plugin to eliminate exposure. Regularly auditing installed WordPress plugins for available updates and applying the principle of least privilege to plugin functionality is recommended (Feedly, Patchstack).
