CVE-2025-22704 is classified as a high-severity vulnerability due to its potential impact on affected systems. This vulnerability allows improper neutralization of input during web page generation, specifically leading to a Cross-Site Scripting (XSS) attack. The affected product is the WordPress Signature plugin developed by Abinav Thakuri, with the issue present in versions up to and including 0.1. The risk to organizations includes the possibility of attackers executing malicious scripts in the context of the user's session, which can lead to unauthorized actions or data exposure. Given the high CVSS score of 7.1, organizations should prioritize patching this vulnerability immediately.
The vulnerability was published on February 3, 2025, and has been categorized under CWE-79, which relates to improper neutralization of input during web page generation. The attack vector is classified as network-based, with low complexity, indicating that an attacker can exploit this vulnerability without advanced technical skills. User interaction is required, which means that the victim must perform some action that triggers the attack, such as clicking a malicious link.
Currently, there are no known exploits available for this vulnerability, and it is not listed in the Known Exploited Vulnerabilities (KEV) database. However, organizations should remain vigilant as the absence of known exploits does not eliminate the risk. The urgency for defenders is high, as the nature of XSS vulnerabilities can lead to severe consequences if not addressed promptly.
Organizations using the affected WordPress Signature plugin should assess their environments immediately and take necessary actions to mitigate this vulnerability.
Vulnerability Details
The CVE-2025-22704 vulnerability is characterized as a Cross-Site Scripting (XSS) vulnerability that allows for reflected XSS attacks in the WordPress Signature plugin. The CVSS score is 7.1, indicating high severity due to the potential impact on confidentiality, integrity, and availability.
This vulnerability affects the WordPress Signature plugin versions from n/a to 0.1. It was reported by audit@patchstack.com and is classified under CWE-79. The publication date for this CVE was February 3, 2025.
Technical Analysis
The root cause of CVE-2025-22704 lies in the improper handling of user input within the WordPress Signature plugin, where user-supplied data is not adequately sanitized before being reflected on web pages. This oversight allows attackers to inject malicious scripts that execute in the context of the user's browser.
The attack vector is network-based, meaning that attackers can exploit this vulnerability remotely. The attack complexity is low, and no privileges are required to exploit it, making it accessible to a wide range of potential attackers. User interaction is necessary, as the victim must engage with the malicious content for the attack to succeed.
The impacts of a successful exploitation include low confidentiality, integrity, and availability impacts, as the attacker can execute scripts that may steal session cookies, redirect users, or perform actions on behalf of the user. Monitoring for unusual behavior and implementing input validation can help mitigate these risks.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2025-22704 is significant, as reflected XSS vulnerabilities are commonly exploited by attackers to compromise users' sessions. If left unaddressed, the potential for data breaches, unauthorized access, and reputational damage increases.
The urgency for organizations to remediate this vulnerability is high due to the CVSS score of 7.1. Organizations should assess their exposure and prioritize patching the affected WordPress Signature plugin as part of their vulnerability management program. The blast radius for potential exploitation can be extensive, affecting users across multiple sessions.
Organizations are advised to implement web application firewalls and input validation measures to protect against similar vulnerabilities in the future.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
All versions of the WordPress Signature plugin prior to version 0.1 are affected by this vulnerability. Organizations should ensure that they are running the latest version to mitigate risks.
Mitigation & Remediation
Organizations should patch the WordPress Signature plugin to its latest version. If a patch is not available, consider implementing web application firewall rules to filter out potentially malicious input.
Monitoring for unusual activity in user sessions can help identify potential exploitation attempts. Additionally, conducting regular security assessments can assist in identifying similar vulnerabilities in the future.
For further guidance on securing web applications, organizations may refer to the application security assessment to validate their security posture.
Detection Guidance
Organizations should monitor logs for indicators of XSS exploitation, including unusual requests that include script tags or unexpected parameters. Behavioral anomalies in user sessions, such as unexpected redirections or unauthorized actions, may also indicate exploitation.
Setting up network signatures to detect patterns consistent with XSS attacks can further enhance detection capabilities.
AppSecure Threat Intelligence Insight
CVE-2025-22704 reflects a broader trend in web application vulnerabilities, particularly the prevalence of XSS flaws in plugins and third-party extensions. As organizations increasingly rely on plugins to enhance functionality, the importance of rigorous security assessments becomes paramount.
Security teams should prioritize the evaluation of third-party components as part of their overall security strategy. For organizations using WordPress, implementing regular vulnerability scanning and penetration testing can provide insights into existing security gaps.
The strategic takeaway from this vulnerability is the need for continuous monitoring and updating of plugins, as well as fostering a security-first culture within development teams to mitigate risks associated with third-party software.
