CVE-2025-23889 describes a high-severity vulnerability classified as Cross-site Scripting (XSS) in the FooGallery Captions plugin for WordPress. This vulnerability allows for reflected XSS attacks, which can be exploited by attackers to execute arbitrary scripts in the context of a user's browser session. The CVSS score of 7.1 signifies a high level of risk, and the potential for exploitation can lead to significant impacts on the confidentiality, integrity, and availability of affected systems.
The vulnerability is specifically present in FooGallery Captions versions from n/a up to and including 1.0.2. As of now, the status of this vulnerability is marked as 'Deferred', indicating that a full resolution might not yet be available. However, organizations using affected versions should prioritize identifying and mitigating this vulnerability due to the risks involved.
Attackers may leverage this vulnerability to inject malicious scripts into web pages, which can lead to session hijacking, defacement of websites, or redirecting users to malicious sites. The fact that user interaction is required for exploitation makes the vulnerability a potential risk that organizations should not overlook. Organizations should prioritize patching immediately.
The urgency for defenders cannot be overstated, especially given the widespread use of the FooGallery Captions plugin in various WordPress installations. Organizations must act quickly to safeguard their environments against potential exploitation of this vulnerability.
Vulnerability Details
The official CVE description states that this vulnerability allows improper neutralization of input during web page generation, leading to reflected XSS. The specific affected product is the FooGallery Captions plugin, with versions ranging from n/a to 1.0.2. The CVSS score of 7.1 indicates a high severity, with the following metrics:
Metric | Value |
|---|---|
Attack Vector | NETWORK |
Attack Complexity | LOW |
Privileges Required | NONE |
User Interaction | REQUIRED |
This vulnerability aligns with the CWE-79 classification, indicating a Cross-site Scripting vulnerability. With such a high CVSS score, organizations must ensure they are not vulnerable to this type of attack.
Technical Analysis
The root cause of CVE-2025-23889 is the improper neutralization of user input during the generation of web pages. Attackers can exploit this vulnerability by injecting malicious scripts that execute in the context of the user's browser when they interact with the affected web application.
The attack vector is over the network, meaning that an attacker can exploit this vulnerability remotely, and the complexity of the attack is low, making it easier for attackers to carry out. No privileges are required to exploit this vulnerability, and user interaction is necessary, as the victim must click on a malicious link or perform an action that triggers the script.
The impact of exploitation is multifaceted. The confidentiality of user data could be compromised as attackers may gain unauthorized access to sensitive information. Similarly, integrity may be affected if an attacker can alter or inject content into the affected web pages. Availability may also be impacted, depending on how the injected scripts are designed to function.
Risk & Impact Analysis
Risk to organizations includes significant exposure to XSS attacks, which could lead to data theft, session hijacking, or even defacement of the affected web applications. Given the high CVSS score of 7.1, organizations should assess the potential blast radius of a successful exploit, especially if the FooGallery Captions plugin is widely used in their environment.
The urgency for remediation is high. Organizations should prioritize addressing this vulnerability in their patch management cycle, especially since the plugin is commonly utilized in many WordPress sites. Delaying action could result in severe security incidents that may have long-lasting repercussions.
Monitoring for attempts to exploit this vulnerability is crucial, as it can help detect malicious activities before they escalate. Organizations should implement logging and alerting mechanisms to track suspicious interactions with the FooGallery Captions plugin.
Exploitation Status
Signal | Status |
