CVE-2025-22518 describes a vulnerability in the PluginsPoint Justified Image Gallery plugin, specifically a Stored Cross-site Scripting (XSS) issue. This vulnerability allows attackers to inject malicious scripts into web pages viewed by users, posing a significant risk to affected applications. The severity level is classified as medium, with a CVSS score of 6.5, indicating that it requires attention but may not be as critical as higher-severity vulnerabilities.
This vulnerability allows attackers to exploit the XSS issue by sending crafted input which is not properly sanitized. If successfully executed, an attacker could manipulate the display of web pages, steal session cookies, or redirect users to malicious sites. The risk to organizations includes potential data theft, loss of user trust, and reputational damage.
Currently, there are no known public exploits for this vulnerability, and it has not been included in the Known Exploited Vulnerabilities (KEV) catalog. However, organizations should remain vigilant as the risk of exploitation still exists, and appropriate patching should be prioritized.
Organizations using the affected version of the Justified Image Gallery plugin should address this vulnerability promptly to mitigate associated risks. The urgency for defenders is significant, and timely remediation is essential to prevent any potential exploitation.
Vulnerability Details
The vulnerability is classified as an improper neutralization of input during web page generation, specifically categorized under CWE-79, which is related to Cross-site Scripting (XSS). The affected product is the Justified Image Gallery plugin, with versions up to and including 1.0 being impacted. The vulnerability was published on January 7, 2025.
Technical Analysis
The root cause of this vulnerability stems from insufficient input validation and sanitization in the Justified Image Gallery plugin. Attackers can exploit this by sending specially crafted input that is then stored and rendered by the application without proper filtering. The attack vector is network-based, indicating that exploitation can occur remotely over the internet.
The attack complexity is classified as low, meaning that an attacker does not require extensive skill or resources to exploit the vulnerability. Additionally, the exploitation requires low privileges and user interaction, as the victim must load the compromised web page. The impact on confidentiality, integrity, and availability is categorized as low.
Risk & Impact Analysis
Organizations should assess the deployment risk associated with this vulnerability. Given the nature of stored XSS, the potential for damage can be significant, particularly if sensitive user data is exposed. The blast radius could include all users interacting with the affected application, leading to widespread ramifications.
The urgency assessment is further amplified by the available CVSS score of 6.5, highlighting that organizations should address this issue in their priority patch cycle. Failure to do so may result in unauthorized access and data exfiltration, underscoring the necessity for immediate action.
