CVE-2025-23559 is a high-severity vulnerability affecting the MemeOne plugin developed by Stepan Stepasyuk. This vulnerability allows for Cross-Site Request Forgery (CSRF), which can lead to stored cross-site scripting (XSS) attacks. The severity is classified as high due to its CVSS score of 7.1, indicating that the potential impact on the confidentiality, integrity, and availability of affected systems is significant.
The vulnerability is categorized under CWE-352, which pertains to CSRF vulnerabilities. With the attack vector being network-based and a low attack complexity, the potential for exploitation is increased, especially since user interaction is required to trigger the exploit.
Organizations using the MemeOne plugin, particularly versions from n/a to 2.0.5, should treat this vulnerability with high urgency. The risk to organizations includes unauthorized actions performed on behalf of authenticated users, leading to data compromise or manipulation.
Given the current status of the vulnerability as deferred, organizations must remain vigilant and monitor for any updates regarding remediation and potential exploits. Immediate action is recommended to mitigate risks associated with this vulnerability.
Vulnerability Details
The CVE-2025-23559 vulnerability allows for CSRF attacks that can result in stored XSS. This issue affects MemeOne versions from n/a through 2.0.5. The CVSS score of 7.1 indicates a high severity level, requiring organizations to address this vulnerability in their patching cycles.
The vulnerability was published on January 16, 2025, and is classified under CWE-352, highlighting its potential for exploitation through CSRF. Organizations should prioritize addressing this vulnerability to prevent exploitation.
Technical Analysis
The root cause of CVE-2025-23559 lies in the inadequacies of the MemeOne plugin's CSRF protection mechanisms. Attackers may leverage this vulnerability to execute unauthorized actions by exploiting the trust that a user has in a given website.
The attack vector is network-based, and the attack complexity is low, requiring no special privileges to exploit the vulnerability. However, user interaction is required to trigger the CSRF attack, which could lead to unauthorized changes in user data.
The impacts on confidentiality, integrity, and availability are categorized as low, but the scope is changed, potentially affecting the broader application environment.
Risk & Impact Analysis
Risk to organizations includes the potential for attackers to perform actions on behalf of legitimate users, leading to unauthorized access and data breaches. The blast radius could extend across all users of the affected plugin versions.
Given the low EPSS score indicating a low probability of exploitation, organizations still need to prioritize addressing this vulnerability due to its inherent risks. The deferred status suggests that while immediate exploitation may not be present, proactive measures should still be considered.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
Affected versions of the MemeOne plugin are those from n/a to 2.0.5. Organizations should ensure that they are using the latest version to mitigate the risks associated with this vulnerability.
Mitigation & Remediation
Organizations should prioritize patching the MemeOne plugin to the latest version available. This may require immediate testing and deployment processes to ensure that risks are mitigated effectively. In environments where immediate patching is not feasible, organizations should consider implementing web application firewalls (WAFs) and other network controls to mitigate CSRF attacks.
For comprehensive security, organizations are encouraged to conduct regular security assessments, such as penetration testing, to uncover similar vulnerabilities and strengthen their security posture.
Detection Guidance
To detect potential exploitation of this vulnerability, organizations should monitor for unusual user activity that may indicate CSRF attempts. Log indicators should include any unauthorized requests made to critical endpoints. Behavioral anomalies in user sessions should also be scrutinized, particularly those that show discrepancies with usual patterns.
AppSecure Threat Intelligence Insight
