The CVSS score for this vulnerability is 7.5, indicating a high risk to organizations that utilize this plugin. The attack vector is classified as network-based, with a high attack complexity. Although no privileges are required for exploitation, user interaction is necessary, which may limit the immediate risk but still requires attention. Organizations using affected versions should take this vulnerability seriously, as it poses a critical threat.
Currently, there are no known exploits or public proof of concepts available, but the potential for such exploitation means that organizations must remain vigilant. Given the high severity and the potential impact of this vulnerability, organizations should prioritize patching immediately.
In summary, CVE-2025-22311 represents a serious security concern for users of the DeluxeThemes Private Messages for UserPro plugin. Immediate action is required to mitigate the risks associated with this vulnerability.
Vulnerability Details
The vulnerability entails improper control of filenames used in PHP include and require statements, leading to remote file inclusion. This issue has been classified under CWE-98, which denotes the failure to properly validate file paths. The last modification date of this vulnerability is April 23, 2026, and it was published on January 21, 2025.
Affected versions include all prior versions up to 4.10.0. The lack of a vendor patch means that organizations must take proactive steps to secure their installations.
Technical Analysis
The root cause of this vulnerability stems from insufficient validation of user-supplied input in the filename parameter of include and require statements. Attackers may exploit this flaw by crafting requests that manipulate the input to include malicious files hosted on external servers. The attack vector being network-based indicates that the vulnerability can be exploited remotely, making it a significant concern for web applications.
The attack complexity is categorized as high, suggesting that successful exploitation may require an understanding of the underlying application logic or specific conditions to be met. No privileges are required to exploit this vulnerability, but user interaction is necessary, which might involve convincing a user to click a malicious link or perform an action that triggers the vulnerability.
This vulnerability affects confidentiality, integrity, and availability, all of which are rated as high. Successful exploitation could allow an attacker to read sensitive files, modify application behavior, or even render the application unavailable.
Risk & Impact Analysis
Organizations utilizing the DeluxeThemes Private Messages for UserPro plugin face substantial risks due to CVE-2025-22311. The potential for remote file inclusion attacks can lead to unauthorized access to sensitive data, including user credentials and private messages. The high attack complexity may deter some attackers, but it does not eliminate the risk entirely.
The urgency to address this vulnerability is underscored by its high severity rating. Organizations should assess their exposure and prioritize remediation as part of their security strategies. The blast radius for this vulnerability is considerable, as any organization using the affected plugin could be targeted, resulting in widespread impact.
Organizations should schedule remediation to ensure that they are protected against potential exploits that may arise as awareness of this vulnerability increases. Given the current absence of known exploits, there remains a window of opportunity for organizations to mitigate risks before they become targeted.
