CVE-2025-58876

Root

Cause

The WordPress Aparat Video Shortcode plugin (versions through 0.2.4) contains a stored cross-site scripting (XSS) vulnerability caused by improper neutralization of user-supplied input during page generation [1]. The plugin fails to sanitize or escape data before output, enabling attackers to inject arbitrary HTML and JavaScript into web pages.

Exploitation

Prerequisites

An attacker must have at least a low-privileged role (such as Contributor or Author) in the WordPress site. While no direct user interaction is required for injection, the stored payload triggers when an authenticated administrator views the page or when any site visitor loads it — making it a stored (persistent) XSS [1].

Impact

Successful exploitation allows the attacker to inject malicious scripts that can perform actions like redirecting visitors to malicious sites, displaying unwanted advertisements, or stealing session cookies. Because the script executes in the context of the vulnerable site, it can be used for further attacks targeting both site administrators and visitors [1].

Mitigation

The vulnerability affects all versions through 0.2.4. The recommended action is to update the plugin to a patched version as soon as one is released. If an immediate update is not possible, site administrators should consult their hosting provider or web developer for temporary workarounds [1].
