CVE-2025-25076 identifies a vulnerability categorized as improper neutralization of input during web page generation, commonly known as a stored cross-site scripting (XSS) vulnerability. This particular issue affects the Graceful Email Obfuscation plugin developed by nicholaswilson, specifically versions from n/a through 0.2.2. The CVSS score for this vulnerability is 6.5, which classifies it as medium severity.
The implications of this vulnerability are significant, particularly in web applications where user-generated content is displayed. Attackers may leverage this vulnerability to execute arbitrary scripts in the context of the victim's browser, potentially leading to unauthorized actions on behalf of the user.
Risk to organizations includes data theft, session hijacking, and phishing attacks targeted at users of the affected plugin. This vulnerability's exploitation status is currently noted as deferred, and organizations should be aware of the need for prompt remediation.
Organizations should prioritize patching immediately to mitigate the risk posed by this vulnerability. It is crucial to monitor the environment for any signs of exploitation, given the nature of stored XSS vulnerabilities.
Vulnerability Details
The official description states that this vulnerability allows for stored XSS within the Graceful Email Obfuscation plugin. The CVSS vector string associated with this vulnerability is CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L. This indicates that the attack vector is network-based, with low attack complexity and requires low privileges and user interaction.
Technical Analysis
The root cause of this vulnerability stems from improper handling of user input during the generation of web pages. The attack vector is primarily network-based, as it exploits the application's failure to sanitize user input effectively, allowing attackers to inject malicious scripts.
The attack complexity is low, as attackers only require the ability to submit data to the application. Privileges required are low, meaning even authenticated users can potentially exploit this vulnerability. User interaction is required for successful exploitation, as the malicious script needs to be executed in the context of another user's browser.
Confidentiality, integrity, and availability impacts are all classified as low, meaning that while this vulnerability can lead to unauthorized actions, the overall effect on the system may be limited depending on the context of use.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2025-25076 is substantial. Organizations utilizing the Graceful Email Obfuscation plugin should be particularly vigilant, as the stored XSS vulnerability could have a wide-reaching impact on their user base.
Given its medium CVSS score, organizations should address this vulnerability in their priority patch cycle. The potential for exploitation increases the urgency of remediation, especially in environments where user data and interactions are prevalent.
The blast radius of this vulnerability can be significant, especially in multi-user environments where one compromised user can potentially impact others. It is crucial to implement a defense-in-depth strategy to mitigate these risks effectively.
