CVE-2025-22802 describes an improper neutralization of input during web page generation vulnerability, specifically a Cross-site Scripting (XSS) issue affecting the add-ons.org Email Templates Customizer for WordPress, known as YeeMail. This vulnerability allows stored XSS, which can compromise user data and application integrity.
The CVSS score for this vulnerability is 6.5, categorizing it as medium severity. The implications of this vulnerability necessitate immediate attention due to its potential for exploitation in web applications. Organizations utilizing the affected version of YeeMail, particularly those running version 2.1.4 or earlier, are at risk.
Risk to organizations includes unauthorized access to sensitive information through stored XSS attacks, which can lead to data breaches and compromised user sessions. Given the nature of this vulnerability, the urgency for defenders is considerable, and organizations should prioritize patching immediately.
Currently, there are no confirmed public exploits or proof of concepts available for this vulnerability. However, organizations must remain vigilant and proactive in their approach to security, particularly in monitoring their web applications for potential exploitation attempts.
Vulnerability Details
The vulnerability allows for improper neutralization of input during web page generation, which can be exploited via stored XSS. The affected product, YeeMail, is a plugin for WordPress that enables users to create email templates. The vulnerability affects versions up to 2.1.4.
The CVSS score reflects the following characteristics: the attack vector is network-based, attack complexity is low, and it requires low privileges with user interaction. The confidentiality, integrity, and availability impacts are all rated as low.
Technical Analysis
The root cause of this vulnerability stems from improper handling of user input in the YeeMail plugin. Attackers may leverage this flaw to inject malicious scripts into web pages, which would then be executed in the context of other users' browsers.
The attack vector is primarily network-based, where an attacker must convince a user to interact with a malicious payload. The attack complexity is low, as it does not require extensive technical skills to exploit. The user interaction requirement indicates that an unsuspecting user must perform an action, such as clicking a link or submitting a form.
While the vulnerability does not necessitate high privileges, it can lead to significant impacts on the confidentiality and integrity of user data, as well as the availability of the application itself.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2025-22802 includes the potential for attackers to exploit stored XSS vulnerabilities to compromise user accounts, leading to unauthorized access and data loss. This vulnerability represents a notable threat to organizations using the YeeMail plugin, as exploitation could result in a significant breach of user privacy and trust.
Organizations must assess the blast radius potential of this vulnerability, which can extend beyond just the affected plugin, potentially impacting other integrated systems and services. Given the medium severity rating, organizations should address this vulnerability in their priority patch cycle.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
The vulnerable versions of the YeeMail plugin extend from an unspecified version up to and including 2.1.4. Organizations using this plugin should ensure they are running a patched version to mitigate the XSS vulnerability.
Mitigation & Remediation
Organizations should patch their installations of the YeeMail plugin to the latest version to remediate this vulnerability. If an immediate update cannot be applied, consider implementing web application firewalls to filter and block malicious input.
For additional security measures, organizations may consider conducting a comprehensive security assessment and engaging in application security assessment to identify any other potential vulnerabilities.
Detection Guidance
To detect attempts to exploit this vulnerability, organizations should monitor logs for unusual patterns of user input, especially in email template submissions. Look for any unexpected scripts or malformed data that could indicate an XSS attempt.
Behavioral anomalies in user interactions with the email templates may also indicate potential exploitation of the vulnerability.
AppSecure Threat Intelligence Insight
While CVE-2025-22802 currently has no known exploits, its existence underscores a critical area of risk for web application developers and operators. The XSS attack vector remains prevalent, and organizations must remain vigilant in their security posture, especially when using third-party plugins.
This vulnerability aligns with broader trends in web application security, where mismanagement of user inputs can lead to significant breaches. Organizations are encouraged to invest in vulnerability management programs and continuous monitoring to mitigate risks associated with third-party integrations.
For organizations leveraging cloud-based services, ensuring security in the development process is paramount. Engaging in cloud penetration testing can provide additional layers of security and help identify vulnerabilities before they are exploited.
