CVE-2025-63041: Forget About Shortcode Buttons Plugin Contributor Access Control Bypass

Technical summary

CVE-2025-63041 is classified as an authorization bypass affecting the Forget About Shortcode Buttons plugin. The vulnerability is rooted in CWE-862 (Missing Authorization), where the plugin fails to properly enforce role-based access control. Authenticated users with the contributor role can craft requests to access or modify functionality restricted to higher-privileged roles (such as editors or administrators). The CVSS v3.1 score of 5.4 reflects a network-accessible vulnerability requiring low complexity exploitation and valid login credentials, with impacts limited to integrity and availability rather than confidentiality.

Business impact

For WordPress sites relying on the Forget About Shortcode Buttons plugin, this vulnerability poses a moderate risk to content integrity and site stability. Malicious or compromised contributor accounts could alter or remove shortcode-related functionality, potentially affecting site layout, user experience, or feature availability. While direct data theft is not a concern, the integrity impact could necessitate content recovery and remediation effort. Sites with many contributors or guest editorial staff face elevated risk if contributor accounts are compromised or if insider threat is a concern.

Affected systems

The vulnerability affects the Forget About Shortcode Buttons WordPress plugin in all versions up to and including 2.1.3. Any WordPress installation using this plugin at a vulnerable version with active contributor-level user accounts is potentially at risk. The scope is limited to sites where the plugin is installed; WordPress core and other plugins are not directly affected.

Exploitability

Exploitation requires valid WordPress credentials with at least contributor-level permissions. An attacker cannot exploit this remotely without authentication. The vulnerability is straightforward to exploit once a contributor account is compromised or is available to a malicious insider—no complex exploitation technique or user interaction is necessary. However, the requirement for valid login credentials significantly limits attack surface in well-managed WordPress environments.

Remediation

The primary remediation is to update the Forget About Shortcode Buttons plugin to a patched version released after 2.1.3. Verify against the official plugin repository or vendor advisory for the specific version number containing the fix. In the interim, consider restricting contributor role assignments to trusted users only, disabling the plugin if it is not actively required, or implementing Web Application Firewall (WAF) rules to monitor for suspicious contributor activity targeting shortcode-related endpoints.

Patch guidance

Monitor the official WordPress plugin repository for an updated release of Forget About Shortcode Buttons addressing this authorization flaw. When a patch becomes available, test it in a staging environment before deploying to production. Given the medium severity and the need for authenticated access, patches can typically be deployed within your standard maintenance window rather than as an emergency hotfix, though earlier deployment is preferable if the plugin is heavily used. Verify patch installation by confirming the plugin version number in the WordPress admin panel.

Detection guidance

Monitor WordPress audit logs and access logs for contributor-level API calls or form submissions targeting shortcode-related admin actions that should require editor or administrator privileges. Implement logging around role-based permission checks within the plugin's functions. If you have a WAF in place, consider rules that flag authenticated requests from low-privilege accounts attempting to access high-privilege endpoints. Security plugins like Wordfence or iThemes Security may provide additional contributor activity monitoring capabilities.

Why prioritize this

Assign this vulnerability medium priority in your remediation queue. While it requires authentication and does not expose data directly, the integrity and availability impacts—combined with the relative ease of exploitation once a contributor account is obtained—warrant timely patching. Prioritize sites with many external contributors, sites with a history of contributor account compromise, or sites where shortcode functionality is critical to operations.

Risk score, explained

The CVSS v3.1 score of 5.4 (Medium) reflects the balance between limiting factors and impact. Authentication is required, reducing exploitability in the wild; however, network accessibility and low complexity keep severity moderate. The vulnerability affects integrity and availability but not confidentiality, preventing a higher score. This is a realistic medium-severity vulnerability that deserves prompt attention but does not typically trigger emergency response protocols.
