CVE-2025-24608 is a high-severity vulnerability found in the Milan Petrovic GD Mail Queue plugin. This vulnerability allows for reflected Cross-Site Scripting (XSS), which can be exploited by attackers to execute arbitrary scripts in a user's browser session. The issue affects all versions of the GD Mail Queue plugin up to version 4.3.
The CVSS score for this vulnerability is 7.1, indicating a high severity level. This score suggests that the vulnerability can be exploited over a network, requiring low attack complexity and no privileges for the attacker. User interaction is required, as the victim must click a malicious link to trigger the vulnerability.
Risk to organizations includes potential data theft, session hijacking, and unauthorized actions performed on behalf of users. Given the characteristics of this vulnerability, organizations using the affected plugin should prioritize immediate remediation.
Currently, there are no known exploits or public proof-of-concept code reported for CVE-2025-24608, but the potential impact remains significant, necessitating prompt attention.
Vulnerability Details
The vulnerability arises from improper neutralization of input during web page generation, specifically allowing reflected XSS attacks. The affected component is the GD Mail Queue plugin, and the CVE was published on January 31, 2025. The CWE classification for this vulnerability is CWE-79.
As noted, the CVSS vector for this vulnerability is CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L, reflecting its high severity and the potential for low complexity attacks.
Technical Analysis
The root cause of this vulnerability lies in the inadequate sanitization of user input, which allows for the injection of malicious scripts into web pages. The attack vector is through the network, and since no privileges are required for exploitation, this vulnerability poses a significant risk to users. User interaction is necessary, as the victim must click on a specially crafted link to exploit the vulnerability.
In terms of impact, the confidentiality, integrity, and availability are rated as low, meaning while the immediate effects may not alter the system's functionality, they can lead to unauthorized access and actions within the user's session.
Risk & Impact Analysis
Organizations utilizing the GD Mail Queue plugin must recognize the real-world risks associated with this vulnerability. The potential for attackers to hijack user sessions and execute unauthorized actions could lead to severe reputational damage and loss of user trust.
With a CVSS score of 7.1, organizations should address this vulnerability in their priority patch cycle. Although there are currently no known active exploits, the nature of XSS vulnerabilities means they can often lead to significant consequences if left unaddressed.
