CVE-2025-22282 is a reflected Cross-site Scripting (XSS) vulnerability identified in the keksdieb ez Form Calculator Premium WordPress plugin, affecting all versions up to and including 2.14.1.2. The vulnerability stems from improper neutralization of input during web page generation, allowing malicious actors to inject arbitrary JavaScript code that is reflected back to users without proper sanitization. This reflected XSS can be triggered when a victim clicks on a specially crafted URL containing malicious payloads. Since the vulnerability is reflected, it requires the victim to interact with the attacker-supplied link, but no authentication is required, increasing the attack surface. Exploitation can lead to theft of session cookies, enabling account takeover, defacement, or redirection to phishing or malware sites. The plugin is commonly used to create interactive calculators on WordPress sites, which are popular globally, increasing the potential reach of this vulnerability. No CVSS score has been assigned yet, and no patches or known exploits are currently documented. The vulnerability was reserved in January 2025 and published in April 2025, indicating recent discovery. The lack of immediate patches necessitates proactive mitigation steps by administrators. The vulnerability highlights the importance of proper input validation and output encoding in web applications to prevent injection attacks. Given the plugin’s role in user interaction and data processing on websites, the risk to confidentiality and integrity is significant if exploited.

The primary impact of CVE-2025-22282 is the compromise of user confidentiality and integrity through the execution of arbitrary scripts in the context of the vulnerable website. Attackers can steal session cookies, enabling unauthorized access to user accounts, potentially leading to data breaches or unauthorized transactions. The vulnerability can also facilitate phishing attacks by redirecting users to malicious sites or displaying fraudulent content, damaging organizational reputation. Although availability impact is limited, the overall trust in the affected website can be severely undermined. Organizations relying on the ez Form Calculator Premium plugin for customer interaction or data collection face increased risk of user data compromise and regulatory non-compliance if personal data is exposed. The ease of exploitation without authentication and the widespread use of WordPress plugins globally amplify the threat’s potential impact. Even though no known exploits are reported yet, the vulnerability’s presence in a popular plugin makes it a likely target for attackers once exploit code becomes available.

1. Monitor for official patches or updates from the keksdieb vendor and apply them promptly once released. 2. Until patches are available, implement Web Application Firewall (WAF) rules to detect and block typical reflected XSS payloads targeting the plugin’s endpoints. 3. Employ strict input validation and output encoding on all user-supplied data, especially in URL parameters processed by the plugin. 4. Use Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of potential XSS attacks. 5. Educate users and administrators about the risks of clicking on untrusted links to reduce the likelihood of successful exploitation. 6. Conduct regular security audits and penetration testing focusing on web application input handling. 7. Consider temporarily disabling or replacing the vulnerable plugin with alternative solutions if immediate patching is not feasible. 8. Monitor logs for suspicious activity that may indicate attempted exploitation attempts.
