info:
|
|
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.
|
|
remediation: |
|
|
Update the WordPress E2Pdf plugin to version 1.16.45 or later to mitigate the vulnerability.
