Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Tom Ewer Easy Tweet Embed easy-tweet-embed allows DOM-Based XSS. This issue affects Easy Tweet Embed: from n/a through <= 1.7.
The CVSS score for this vulnerability is 6.5, categorizing it as medium severity. This indicates that while the risk is significant, it may not be as pressing as higher severity vulnerabilities. However, organizations should recognize that even medium-severity vulnerabilities can be leveraged by attackers in the right circumstances.
Risk to organizations includes unauthorized access to sensitive user data and potential site manipulation due to the DOM-Based XSS nature of this vulnerability. Attackers may leverage this flaw if it is not addressed, making it critical for users of the Easy Tweet Embed plugin to take immediate action.
Organizations should prioritize patching immediately. Given that this vulnerability has a known exploitability status, it is crucial to take action before attackers can exploit the weakness.
Vulnerability Details
The vulnerability is classified as Cross-site Scripting (XSS) under CWE-79. It affects Easy Tweet Embed versions from n/a through 1.7, as published on January 16, 2025. The vulnerability's nature allows attackers to execute arbitrary JavaScript in the context of the user's browser.
The CVSS score of 6.5 indicates a medium severity level, characterized by a network attack vector, low attack complexity, and the requirement for low privileges and user interaction.
Technical Analysis
The root cause of this vulnerability lies in improper input handling during web page generation. As a result, attackers can inject malicious scripts that execute in the context of users accessing the affected web pages.
This vulnerability is exploitable via network interactions, requiring a low level of complexity and privileges. User interaction is also required, as victims must visit a malicious page or trigger the execution context.
Risk & Impact Analysis
The real-world risk is significant for organizations that utilize the Easy Tweet Embed plugin. Attackers could exploit this vulnerability to execute scripts in the context of other users, potentially leading to data theft, session hijacking, or unauthorized actions performed on behalf of the user.
The blast radius for this vulnerability primarily affects users accessing the site where the plugin is deployed, which may include a broad audience depending on the site's reach. Therefore, organizations should assess their exposure and prioritize remediation.
Given the CVSS score and the fact that the vulnerability is not included in the KEV catalog, the urgency for remediation is categorized as medium. Organizations should schedule remediation as part of their regular patch management cycle.
