CVE-2025-23865 identifies a medium severity vulnerability within the Pressfore Winning Portfolio plugin, specifically a stored Cross-site Scripting (XSS) issue. This vulnerability allows attackers to inject malicious scripts into web pages, which can be executed by users visiting those pages. The vulnerability has been classified under the Common Weakness Enumeration (CWE) as CWE-79, indicating improper neutralization of input during web page generation. Given that the CVSS score for this vulnerability is 6.5, it is essential for organizations using this plugin to address it urgently.
The potential impact of this vulnerability could lead to unauthorized access to sensitive data, disruption of services, and damage to the organization’s reputation. As the vulnerability is present in versions of the Winning Portfolio plugin from an unspecified date through version 1.1, organizations should ascertain their current version status to determine exposure.
Currently, there is no public information indicating that exploits for this vulnerability are available. However, organizations should not assume that this will remain the case. The urgency for defenders lies in the fact that stored XSS vulnerabilities are particularly concerning due to their potential to affect all users of the affected application.
Organizations must prioritize patching immediately to mitigate risks associated with CVE-2025-23865. Remediation efforts should focus on updating the Winning Portfolio plugin to the latest version, along with implementing security best practices to prevent future vulnerabilities.
Vulnerability Details
The vulnerability, classified as a stored Cross-site Scripting (XSS), allows attackers to inject malicious JavaScript into web pages viewed by users of the Winning Portfolio plugin. This issue affects versions of the plugin from an unspecified date through version 1.1.
The CVSS score associated with this vulnerability is 6.5, categorized as medium severity, indicating that while the vulnerability is not critical, it carries significant risk. The attack vector is defined as network-based, with low complexity required for exploitation, and it necessitates user interaction for successful execution.
The vulnerability is further detailed through its CVSS vector string: CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L. This indicates that the attack requires low privileges and user interaction, with the potential for scope change and low impact on confidentiality, integrity, and availability.
Technical Analysis
The root cause of CVE-2025-23865 lies in the improper validation of user input within the pressfore Winning Portfolio plugin. Attackers can exploit this by injecting malicious scripts that execute in the context of the victim's browser when the compromised web page is viewed.
The attack vector is network-based, indicating that the attacker can exploit the vulnerability remotely. The complexity of the attack is low, suggesting that it can be executed without advanced technical skills. Additionally, the privilege required to exploit the vulnerability is low, allowing attackers to potentially leverage it without extensive permissions.
User interaction is required for successful exploitation, meaning that the victim must visit the compromised page, which can be achieved through phishing or social engineering tactics. The confidentiality impact is rated as low, as the attacker may gain limited access to sensitive information, while integrity and availability impacts are also rated low.
Risk & Impact Analysis
Organizations deploying the Winning Portfolio plugin should be aware of the real-world risks associated with CVE-2025-23865. The potential for stored XSS could lead to significant consequences, as attackers may exploit this vulnerability to execute scripts in the context of the victim's browser.
The blast radius of this vulnerability includes all users of the affected application who interact with the compromised web pages. The urgency of addressing this issue is heightened by the fact that it has been classified as medium severity, with a CVSS score of 6.5. Organizations should also take into consideration the context of their deployment, as vulnerabilities with similar characteristics could indicate a broader trend of exploitation.
Organizations should address this vulnerability in their priority patch cycle to minimize the risk of exploitation. The existence of known vulnerabilities that can be exploited through stored XSS can lead to data breaches, loss of user trust, and regulatory penalties.
