DescriptionCVE.org

Cross-Site Request Forgery (CSRF) vulnerability in PluginUs.Net BEAR allows Cross Site Request Forgery.

This issue affects BEAR: from n/a through 1.1.5.

AnalysisAI

Cross-site request forgery (CSRF) in PluginUs.Net BEAR plugin versions up to 1.1.5 allows unauthenticated remote attackers to perform unauthorized actions on behalf of authenticated users through crafted web requests. The vulnerability requires user interaction (clicking a malicious link) but can modify application state without the user's knowledge or consent. No active exploitation has been publicly confirmed at the time of analysis.

Technical ContextAI

CSRF vulnerabilities arise when an application fails to implement proper anti-CSRF tokens or validation mechanisms (CWE-352). The BEAR plugin, identified via CPE cpe:2.3:a:pluginus.net:bear:*:*:*:*:*:*:*:*, appears to be a WordPress plugin for bulk editing operations. When a WordPress plugin lacks CSRF protection on state-changing operations (POST, PUT, DELETE requests), an attacker can forge requests that execute in the context of an authenticated user's browser session, allowing unauthorized modifications to site data, settings, or content without the user's explicit consent.

RemediationAI

Upgrade PluginUs.Net BEAR plugin to version 1.1.6 or later once released by the vendor. Until a patched version is available, apply these compensating controls: (1) Implement WordPress security plugins that provide CSRF token enforcement (e.g., Wordfence, Sucuri) with minimal performance impact, (2) Restrict plugin access to trusted user roles only and limit administrative functions to specific IP addresses or VPN networks to reduce social engineering surface, (3) Disable the BEAR plugin entirely if bulk editing is not actively in use, or (4) Monitor WordPress audit logs for unexpected state changes via the plugin.
