CVE-2024-54398 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the Flaming Forms plugin by jcaruso001, affecting versions up to 1.0.1. Flaming Forms is a WordPress plugin used to create customizable forms on websites. The vulnerability allows an attacker to trick an authenticated user into submitting unauthorized requests to the server, exploiting the lack of proper CSRF protections. This can lead to Stored Cross-Site Scripting (XSS), where malicious scripts are injected and stored within the application’s data, later executed in the context of other users’ browsers. The combination of CSRF and Stored XSS significantly increases the attack surface, as CSRF enables the attacker to bypass normal user interaction restrictions, while Stored XSS can compromise user sessions, steal cookies, or perform actions on behalf of users. The vulnerability does not have a CVSS score yet and no public exploits have been reported. However, the technical details indicate that the flaw arises from insufficient validation of requests and inadequate anti-CSRF tokens in the plugin’s form handling logic. This vulnerability affects all installations of Flaming Forms up to version 1.0.1, which are commonly deployed in WordPress environments. The attack requires the victim to be logged in and visit a maliciously crafted webpage, which then triggers the CSRF attack to inject persistent malicious scripts. The lack of patches currently necessitates immediate defensive measures by administrators.

The impact of CVE-2024-54398 is significant for organizations using Flaming Forms in their WordPress sites. Successful exploitation can lead to persistent Stored XSS, allowing attackers to execute arbitrary JavaScript in the context of users’ browsers, potentially stealing sensitive information such as session cookies, credentials, or personal data. This compromises confidentiality and integrity of user data and can facilitate further attacks like session hijacking or privilege escalation. The CSRF aspect means attackers can perform unauthorized actions on behalf of authenticated users without their consent, potentially modifying form data or site configurations. For organizations relying on Flaming Forms for customer interactions or data collection, this could result in data breaches, reputational damage, and regulatory non-compliance. Since Flaming Forms is a plugin used globally, the threat extends to any website using it, especially those with high user interaction or sensitive data processing. The absence of known exploits reduces immediate risk but does not eliminate the threat, as attackers may develop exploits once details are public. The vulnerability could also be leveraged as part of multi-stage attacks targeting web infrastructure.

To mitigate CVE-2024-54398, organizations should first monitor for official patches or updates from the Flaming Forms developer and apply them promptly once available. Until a patch is released, administrators should consider disabling the Flaming Forms plugin or restricting its use to trusted users only. Implementing Web Application Firewall (WAF) rules to detect and block CSRF attack patterns can provide interim protection. Site owners should ensure that all forms include anti-CSRF tokens and validate these tokens server-side to prevent unauthorized requests. Input validation and output encoding should be enforced rigorously to prevent Stored XSS payloads from being saved or rendered. Additionally, educating users about the risks of visiting untrusted websites while authenticated can reduce the likelihood of CSRF exploitation. Regular security audits and penetration testing focusing on web forms and plugins can help identify similar vulnerabilities early. Monitoring logs for unusual form submissions or script injections can aid in early detection of exploitation attempts.
