The vulnerability identified as CVE-2025-26547 pertains to a Cross-Site Request Forgery (CSRF) flaw in the My Login Logout Plugin, which is susceptible to stored Cross-Site Scripting (XSS) attacks. This issue affects versions of the plugin up to and including version 2.4. Given the nature of the vulnerability, organizations using this plugin are at risk of unauthorized actions being executed without the user's consent.
The CVSS score for this vulnerability is 7.1, classifying it as high severity. This score indicates a significant risk to organizations, especially considering the potential for exploitation via network vectors, which can lead to unauthorized data access and manipulation. The requirement for user interaction adds another layer of complexity, necessitating that an attacker entice a user to perform a specific action.
Organizations should prioritize patching immediately. The risk of exploitation is heightened due to the low attack complexity and the potential impacts on confidentiality, integrity, and availability, albeit categorized as low.
Currently, there are no known exploits or public proofs of concept available for this vulnerability, but the potential for future exploitation remains a concern. Security teams should monitor this vulnerability closely and assess their exposure.
The urgency of remediation cannot be overstated. Organizations must ensure they are not using vulnerable versions of the plugin and should apply any available patches as soon as possible.
Vulnerability Details
CVE-2025-26547 is characterized as a Cross-Site Request Forgery (CSRF) vulnerability that allows for stored XSS attacks. The official description indicates that the flaw exists within the My Login Logout Plugin, affecting versions from n/a up to and including version 2.4. The vulnerability has a CVSS score of 7.1, denoting a high severity level due to its potential impact on confidentiality, integrity, and availability.
The vulnerability has been categorized under CWE-352, which pertains to Cross-Site Request Forgery. The attack vector is classified as NETWORK, with low complexity and no privileges required for exploitation. User interaction is necessary, which means attackers need to trick users into performing actions that trigger the vulnerability.
Technical Analysis
The root cause of this vulnerability stems from insufficient validation of requests, allowing attackers to craft malicious requests that exploit the CSRF weakness. The attack vector primarily involves network interactions where users are tricked into clicking on links or buttons that execute the attack.
The attack complexity is low, meaning that the steps required for an attacker to exploit this vulnerability are minimal. No privileges are required to execute this attack, and user interaction is needed, which can be easily manipulated in many scenarios. The impacts on confidentiality, integrity, and availability are categorized as low, but the implications of a successful exploit can still be significant.
Risk & Impact Analysis
The deployment of the My Login Logout Plugin in production environments poses a considerable risk due to the CSRF vulnerability. Attackers may leverage this vulnerability to execute unauthorized actions on behalf of users, potentially leading to data exposure or manipulation.
The risk to organizations includes potential unauthorized access to sensitive data, as well as the integrity of user sessions being compromised. The blast radius for this vulnerability can be significant, particularly in environments where user accounts hold elevated permissions.
Given the high CVSS score and the presence of user interaction as a necessary component for exploitation, organizations should assess this vulnerability with urgency. The Epsilon Probability Score System (EPSS) indicates a score of 0.000960000, placing it in the 0.26 percentile, suggesting a lower likelihood of exploitation in the near term, but vigilance is still warranted.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
The My Login Logout Plugin is affected from n/a through version 2.4. Organizations should ensure they are using a version that has been patched against this vulnerability.
Mitigation & Remediation
Organizations must ensure they are using the latest version of the My Login Logout Plugin that addresses this vulnerability. If a patch is not available, consider implementing workarounds such as disabling the plugin until an update can be applied.
In addition to updating the plugin, organizations should enforce configuration hardening measures and employ network controls to limit exposure to potential CSRF attacks. Regular monitoring for anomalous behavior can also help in early detection of any exploitation attempts.
For comprehensive assessment and validation of security posture, organizations may benefit from utilizing penetration testing services.
Detection Guidance
To detect potential exploitation attempts related to this vulnerability, organizations should monitor logs for unusual request patterns that may indicate CSRF attempts. Additionally, tracking behavioral anomalies in user sessions can provide insights into unauthorized actions.
Implementing network signatures that flag requests exhibiting characteristics of CSRF attacks can also enhance detection capabilities. Regular audits of system changes and user interactions can further assist in identifying potential security breaches.
AppSecure Threat Intelligence Insight
CVE-2025-26547 highlights the ongoing challenge of securing web applications against CSRF vulnerabilities. It serves as a reminder of the importance of implementing robust security measures, including token-based CSRF protection mechanisms.
Organizations should take this opportunity to review their application security practices and ensure that all web applications are properly configured to mitigate CSRF risks. Regularly updating plugins and frameworks is critical to maintaining a secure environment.
For a deeper understanding of application security, teams may find it beneficial to explore resources on web application penetration testing and best practices in vulnerability management.
Furthermore, understanding the implications of CSRF attacks can empower organizations to better defend against them. Engaging in vulnerability management programs will also aid in establishing a culture of security awareness and proactive risk management.
