CVE-2025-53444 is a medium-severity Cross-Site Request Forgery (CSRF) vulnerability in the DeluxeThemes Userpro plugin. This vulnerability allows attackers to perform unauthorized actions on behalf of users without their consent. The issue affects versions of Userpro up to, but not including, version 5.1.11. As such, organizations using this plugin should take immediate action to mitigate the risk associated with this vulnerability.
The CVSS score for this vulnerability is 4.3, placing it in the medium severity category. Its attack vector is classified as network-based with low complexity, meaning that an attacker can exploit this vulnerability remotely with minimal effort. User interaction is required for the attack to succeed, as the victim must visit a malicious website that sends requests to the vulnerable application.
Risk to organizations includes potential unauthorized actions performed on behalf of legitimate users, which could lead to data compromise and loss of integrity. Given the nature of CSRF attacks, the impact can be significant if left unaddressed. Organizations should prioritize patching immediately to reduce their exposure to potential exploits.
Currently, there are no known public exploits or proofs of concept for this vulnerability, and it has not been classified as actively exploited in the wild. However, the potential for abuse remains, and organizations should remain vigilant.
Vulnerability Details
The vulnerability is identified as a Cross-Site Request Forgery (CSRF) issue as per CWE-352. The official description indicates that the problem exists in the DeluxeThemes Userpro plugin, which allows unauthorized requests to be executed on behalf of authenticated users. The affected versions are those prior to 5.1.11, which means organizations using earlier versions are at risk.
The CVSS score of 4.3 underscores the medium severity of this vulnerability, which is compounded by the requirement for user interaction. The attack complexity is low, facilitating exploitation by attackers who can craft malicious requests that target vulnerable instances of the plugin.
Technical Analysis
The root cause of this vulnerability lies in the inadequate validation of requests made to the Userpro plugin. CSRF vulnerabilities occur when an application does not sufficiently verify that a request originates from an authenticated user, allowing attackers to exploit this failure.
The attack vector is network-based, and since user interaction is required, an attacker must convince the victim to click a malicious link. This could be achieved through phishing or social engineering tactics. The attack complexity is categorized as low, meaning that even less-skilled attackers could potentially exploit this vulnerability.
Regarding impacts, the confidentiality impact is none, but there is a low integrity impact since unauthorized requests can alter user data. The availability impact is also none, indicating that the exploit does not disrupt service availability.
Risk & Impact Analysis
Organizations that deploy the affected versions of the DeluxeThemes Userpro plugin are at risk of unauthorized actions being performed on behalf of legitimate users. The potential for attacks exploiting this CSRF vulnerability poses a significant threat, especially in environments where user data integrity is paramount.
The blast radius of such an exploit could encompass sensitive user actions, leading to data loss or unauthorized modifications. Organizations should assess their risk exposure based on their deployment of the Userpro plugin and understand the urgency of remediation.
Given the current CVSS score and the absence of any active exploitation, organizations should address this vulnerability in their priority patch cycle. While it’s not currently being exploited, the nature of CSRF vulnerabilities means they can be easily weaponized.

Affected Versions
The affected versions of the DeluxeThemes Userpro plugin are all versions prior to 5.1.11. Organizations using this plugin should verify their current versions and implement necessary updates or patches to mitigate this vulnerability.
Mitigation & Remediation
Organizations are advised to update the DeluxeThemes Userpro plugin to version 5.1.11 or later to remediate this vulnerability. If immediate patching is not possible, consider implementing temporary workarounds such as enforcing CSRF tokens for sensitive actions and validating the origin of requests.
Additionally, organizations should strengthen their web application firewall (WAF) rules to detect and block suspicious requests that may exploit this vulnerability. Regular security assessments and adherence to secure coding practices can further mitigate the risk of similar vulnerabilities.
For comprehensive security reviews, organizations can consider leveraging penetration testing services to identify potential weaknesses.
Detection Guidance
Organizations should monitor logs for unusual patterns of request behavior, especially requests that do not originate from valid user sessions. Behavioral anomalies such as unexpected actions performed without user intent should also be flagged for review.
Additionally, network signatures that identify malicious CSRF attacks could be beneficial in blocking potential exploitation attempts. Regular audits of web application security can help in identifying misconfigurations that may lead to CSRF vulnerabilities.
AppSecure Threat Intelligence Insight
The long-term significance of this vulnerability lies in the commonality of CSRF attacks in web applications. They represent a critical attack vector that can easily exploit user trust. Security teams must emphasize the importance of implementing robust defenses against CSRF vulnerabilities.
This vulnerability highlights the need for continuous security education and awareness within development teams, as even minor oversights can lead to significant security lapses. Organizations can benefit from adopting a penetration testing methodology to proactively identify and address potential vulnerabilities.
Moreover, understanding the patterns of vulnerabilities, such as those found in CSRF attacks, can guide future development practices. Security teams should focus on integrating security from the beginning of the development lifecycle, ensuring that security controls are not an afterthought.
For further insights into security vulnerabilities and best practices, organizations can explore additional resources on vulnerability management programs and security testing best practices to strengthen their defenses.
