CVE-2025-1489: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in marcelismus WP-Appbox
The WP-Appbox plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's appbox shortcode in all versions up to, and including, 4.5.4 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
AI Analysis
Technical Summary
CVE-2025-1489 is a stored cross-site scripting vulnerability in the WP-Appbox WordPress plugin (versions up to 4.5.4). It results from improper neutralization of input during web page generation (CWE-79), specifically due to insufficient sanitization and escaping of user-supplied attributes in the appbox shortcode. Authenticated attackers with contributor-level or higher privileges can inject arbitrary scripts that execute when the page is viewed, potentially compromising user sessions or site integrity. The vulnerability has a CVSS 3.1 score of 6.4 (medium severity). No patch or official fix has been documented in the provided data.
Potential Impact
An attacker with contributor-level or higher access can inject persistent malicious scripts into pages via the appbox shortcode. These scripts execute in the context of any user viewing the page, potentially leading to session hijacking, unauthorized actions, or data theft. The vulnerability does not affect availability but impacts confidentiality and integrity. No known active exploitation has been reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, limit contributor-level access to trusted users only.
