This cross-site request forgery vulnerability in Live Composer Team Page Builder represents a significant security risk that allows authenticated users to be tricked into performing unintended actions on vulnerable websites. The flaw exists within the plugin's handling of requests that should require proper authentication and validation mechanisms. The vulnerability affects all versions from the initial release through 1.5.35, indicating a prolonged period during which the security gap remained unaddressed. This type of vulnerability falls under CWE-352, which specifically addresses Cross-Site Request Forgery conditions where web applications fail to validate that requests originate from legitimate sources. The issue enables attackers to manipulate authenticated users into executing actions without their knowledge or consent, potentially leading to unauthorized changes in website configuration or data manipulation.
The technical implementation of this CSRF vulnerability stems from the absence of proper anti-forgery tokens or other validation mechanisms within the plugin's request processing flow. When users access the WordPress admin interface while authenticated, the plugin fails to adequately verify the authenticity of requests submitted through forms or API endpoints. This weakness allows an attacker to craft malicious requests that appear to originate from legitimate administrative actions, exploiting the trust relationship between the user's browser and the vulnerable web application. The vulnerability operates through standard CSRF attack patterns where attackers leverage the user's existing authenticated session to perform unauthorized operations. This attack vector aligns with ATT&CK technique T1566.001 which describes the use of phishing techniques to execute CSRF attacks against authenticated users.
The operational impact of this vulnerability extends beyond simple data manipulation to potentially compromise entire website functionalities and user data integrity. An attacker could exploit this weakness to modify team member information, alter page layouts, or even disable critical website features through unauthorized administrative actions. The vulnerability particularly affects WordPress environments where Live Composer Team Page Builder is installed, creating a persistent threat vector that remains active until the plugin is updated to include proper CSRF protection mechanisms. Organizations using this plugin face the risk of unauthorized modifications to their website content, potential data exposure, and possible compromise of user accounts that rely on the plugin's functionality. The attack surface is particularly concerning because it requires minimal user interaction beyond visiting a malicious site or clicking a compromised link, making it a stealthy threat that can persist undetected for extended periods.
Mitigation strategies for this vulnerability should prioritize immediate plugin updates to versions that include proper CSRF token implementation and request validation. Administrators must ensure all users are running the latest available version of the plugin, which should incorporate anti-forgery token generation and verification mechanisms. The recommended approach involves implementing proper nonce validation for all administrative actions within the plugin's codebase, following WordPress security best practices for CSRF protection. Organizations should also consider implementing additional monitoring and logging mechanisms to detect unauthorized administrative activities that might indicate exploitation attempts. Network-level protections such as web application firewalls can provide additional layers of defense, though they cannot fully compensate for the underlying code vulnerability. Security teams should conduct thorough vulnerability assessments to identify any other plugins or components that might share similar CSRF implementation flaws, ensuring comprehensive protection across the entire WordPress installation.
