|
name: WordPress E2Pdf <1.16.45 - Cross-Site Scripting
|
|
author: theamanrawat
|
|
severity: medium
|
|
description: |
|
|
WordPress E2Pdf plugin before 1.16.45 contains a cross-site scripting vulnerability. The plugin does not sanitize and escape some of its settings, even when the unfiltered_html capability is disallowed. An attacker can inject arbitrary script in the browser of an unsuspecting user in the context of the affected site, making it possible to steal cookie-based authentication credentials and launch other attacks.
|
|
impact: |
|
|
Successful exploitation of this vulnerability could allow an attacker to inject malicious scripts into web pages viewed by users, leading to potential data theft, session hijacking, or defacement of the affected website.
|
|
remediation: |
|
|
Update the WordPress E2Pdf plugin to version 1.16.45 or later to mitigate the vulnerability.
