Organizations should prioritize patching immediately.
Vulnerability Details
The vulnerability allows for Cross-Site Request Forgery (CSRF) attacks, enabling unauthorized commands to be executed on behalf of authenticated users. The CVSS score of 4.3 indicates a medium severity level, suggesting that while the risk is present, it may not be immediately critical, but organizations should take it seriously.
The affected product is the FluentSMTP plugin, specifically versions from n/a through 2.2.80. This vulnerability was published on January 24, 2025.
The associated CWE classification is CWE-352, which pertains to Cross-Site Request Forgery (CSRF).
Technical Analysis
The root cause of this vulnerability lies in the lack of proper validation of user requests within the FluentSMTP plugin. Attackers may leverage this vulnerability by crafting malicious requests that can be sent to the server, tricking it into executing unauthorized actions.
The attack vector is network-based, and the attack complexity is low, meaning that an attacker does not need extensive technical skills to exploit this vulnerability. The privileges required are none, and user interaction is required to trigger the CSRF attack.
In terms of impact, the confidentiality impact is none, while integrity impact is low, and availability impact is none. This indicates that while the attacker may not gain access to sensitive data, they can alter the integrity of user actions.
Risk & Impact Analysis
The real-world deployment risk associated with this vulnerability is moderate. Organizations that use the FluentSMTP plugin should assess their exposure, especially if the application processes sensitive data or allows critical operations.
Given the current CVSS score of 4.3, organizations should address this vulnerability in their priority patch cycle. If left unaddressed, the blast radius could extend to users who interact with the impacted plugin, potentially leading to unauthorized actions being performed in web applications.
Organizations should prioritize patching immediately.
