CVE-2025-11870: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in dmbarber Simple Business Data
The Simple Business Data plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'simple_business_data' shortcode attributes in all versions up to, and including, 1.0.1. This is due to the plugin not properly sanitizing user input or escaping output when embedding the `type` attribute into the `class` attribute in rendered HTML. 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-2025-11870 is a stored cross-site scripting vulnerability in the Simple Business Data WordPress plugin (up to version 1.0.1). The issue arises from improper neutralization of input (CWE-79) in the 'simple_business_data' shortcode attributes, where the 'type' attribute is embedded into the HTML class attribute without proper sanitization or escaping. This allows authenticated users with contributor-level privileges or higher to inject arbitrary JavaScript code that executes in the context of users viewing the compromised pages.
Potential Impact
An attacker with contributor-level access or higher can inject persistent malicious scripts into pages using the vulnerable shortcode. These scripts execute in the browsers of users who visit the affected pages, potentially leading to session hijacking, defacement, or other client-side attacks. The vulnerability does not affect availability but impacts confidentiality and integrity of user sessions and data.
Mitigation Recommendations
No official patch or fix is currently available for this vulnerability. Users should monitor the vendor's advisory channels for updates. As a temporary mitigation, restrict contributor-level access to trusted users only and consider disabling or removing the Simple Business Data plugin until a fix is released.
