CVE-2025-53320

Vulnerability

Description

The Free Downloads EDD WordPress plugin, through version 1.0.4, fails to properly neutralize user input during web page generation, leading to a DOM-based Cross-Site Scripting (XSS) vulnerability. This is a classic improper input handling issue where attacker-controlled data is reflected in the page without sanitization [1].

Exploitation

Attackers can exploit this flaw without needing authentication or advanced privileges. The vulnerability is triggered when a victim user (such as a site administrator) interacts with a crafted link, visits a malicious page, or submits a specially designed form. This user interaction is the only prerequisite for successful exploitation [1].

Impact

Successful exploitation allows an attacker to inject arbitrary JavaScript, HTML, or other malicious payloads into the vulnerable site. These scripts execute in the context of the victim's browser when they visit the affected page. Potential consequences include redirects to malicious sites, injection of unwanted advertisements, theft of sensitive session data, or other harmful actions that can compromise both site visitors and administrators [1].

Mitigation

The vendor has not released a patched version, as the plugin is end-of-life (EOL). Users are strongly advised to immediately update the plugin if a newer version exists, or to remove it entirely. If removal is not possible, contacting a hosting provider or web developer for assistance is recommended. This vulnerability is known to be used in mass-exploit campaigns targeting thousands of sites [1].
