The vulnerability identified as CVE-2025-24636 is a high-severity Cross-Site Request Forgery (CSRF) vulnerability found in the Rick Laymance MachForm Shortcode plugin. This vulnerability allows for stored Cross-Site Scripting (XSS) attacks, which can have serious implications for affected systems. The severity of this vulnerability is classified as high, with a CVSS score of 7.1. It is crucial for organizations using this plugin to understand the risks involved and take immediate action.
This vulnerability allows attackers to exploit the MachForm Shortcode plugin, which affects versions from n/a through 1.4.1. The potential for exploitation is significant, as it can lead to unauthorized actions being performed on behalf of users who are tricked into interacting with malicious requests.
Organizations should prioritize addressing this vulnerability in their patch management processes due to the risks it poses. The urgency to remediate is underscored by the fact that user interaction is required for exploitation, making social engineering tactics a viable attack vector.
Immediate action is advised to mitigate the risks associated with CVE-2025-24636, as failure to address this vulnerability could lead to unauthorized access and compromise sensitive data.
Vulnerability Details
CVE-2025-24636 is classified under CWE-352, which corresponds to Cross-Site Request Forgery (CSRF). The CVSS vector for this vulnerability is CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L, indicating that the attack can be executed over a network with low complexity and no privileges required from the attacker. The integrity, confidentiality, and availability impacts are all rated as low.
Technical Analysis
The root cause of this vulnerability lies in the improper handling of CSRF tokens within the MachForm Shortcode plugin. Attackers can exploit this flaw by crafting malicious requests that are executed under the context of a logged-in user. The attack vector is categorized as network-based, with low complexity involved in crafting the exploit.
The attack requires user interaction, meaning that an attacker must trick the target user into clicking a link or performing an action that submits a request to the vulnerable application. While this vulnerability does not require elevated privileges, the impact can lead to unauthorized actions being performed on behalf of the user, including potential data theft or manipulation.
Risk & Impact Analysis
Risk to organizations includes the potential for unauthorized access to sensitive data and the execution of malicious actions within the context of legitimate user accounts. The blast radius of this vulnerability includes all users of the MachForm Shortcode plugin, particularly those with administrative privileges, who may inadvertently authorize actions that compromise system integrity.
Given the CVSS score of 7.1, organizations should address this vulnerability in their priority patch cycle. Although it may not be actively exploited in the wild, the possibility remains for attackers to leverage social engineering techniques to exploit this weakness.

Affected Versions
All versions of the MachForm Shortcode plugin prior to 1.4.1 are affected by this vulnerability. Organizations using this plugin should assess their current version and apply necessary patches as soon as possible.
Mitigation & Remediation
Organizations should prioritize patching the MachForm Shortcode plugin to version 1.4.2 or later, where this vulnerability has been addressed. If immediate patching is not possible, consider implementing temporary workarounds such as disabling the plugin until a secure version can be deployed.
Configuration hardening of web applications that utilize this plugin can also reduce the attack surface. Monitoring user interactions and establishing network controls can help identify potential exploitation attempts.
Continuous security testing can be beneficial to validate the effectiveness of these measures and ensure ongoing protection.
Detection Guidance
Organizations should monitor logs for unusual requests that could indicate CSRF attempts. Behavioral anomalies such as unexpected user actions or multiple requests from the same user session should be scrutinized.
Network signatures that detect abnormal traffic patterns associated with CSRF attacks can also be implemented. Ensure that security teams are aware of the specific behaviors to watch for in user interactions.
AppSecure Threat Intelligence Insight
