Overview
CVE-2025-66106 identifies a missing authorization vulnerability within the WordPress Featured Post Creative plugin. This flaw, categorized as “Exploiting Incorrectly Configured Access Control Security Levels,” allows attackers to potentially bypass intended access restrictions and perform unauthorized actions. The affected plugin versions range from n/a up to and including version 1.5.5.
Technical Details
The vulnerability stems from a lack of proper authorization checks within the Featured Post Creative plugin. Specifically, certain functionalities or endpoints within the plugin do not adequately verify the user’s permissions before allowing access. This means an attacker, potentially with low-level privileges or even unauthenticated, could manipulate requests to access or modify data they shouldn’t be allowed to.
While the exact vulnerable endpoint is not specified here, the reference link provides greater technical context to the actual function call or functionality that suffers the Broken Access Control.
CVSS Analysis
Currently, both the Severity and CVSS score are listed as N/A. While a CVSS score is not yet available, the “Missing Authorization” description highlights the risk. Until a CVSS score is assigned, it is vital to treat this vulnerability with caution, based on the information at hand. It’s highly recommended to update the plugin or remove it from your website.
Possible Impact
The potential impact of CVE-2025-66106 could be significant, potentially allowing an attacker to:
- Modify featured post settings without authorization.
- Potentially inject malicious code into featured posts.
- Gain unauthorized access to sensitive plugin data.
- Escalate privileges within the WordPress installation (depending on the specific vulnerability).
Mitigation or Patch Steps
The primary mitigation step is to immediately update the Featured Post Creative plugin to the latest version, if a version newer than 1.5.5 is available. The plugin developer should release a patch that addresses the missing authorization vulnerability.
If an update is not yet available, consider the following interim steps:
- Disable the Featured Post Creative plugin. This will eliminate the vulnerability but also remove the plugin’s functionality.
- Monitor plugin updates closely. As soon as an update is released, apply it promptly.
- Consult security best practices. It is generally a good practice to only use plugins from reliable sources. Also, a Web Application Firewall (WAF) might help prevent the exploit by detecting malicious requests to the vulnerable endpoint.
