CVE-2025-39409

Vulnerability

Description

The WordPress Video Robot - The Ultimate Video Importer plugin, versions n/a through 1.20.0, contains a reflected cross-site scripting (XSS) vulnerability. This flaw stems from improper neutralization of user-supplied input during web page generation, allowing an attacker to inject arbitrary malicious scripts into web pages [1].

Exploitation

Details

The vulnerability is classified as reflected XSS, meaning the attack payload is delivered via a crafted request (e.g., a malicious link) that is then reflected back to the user's browser. Exploitation requires user interaction, such as a privileged user clicking a specially crafted link, visiting a malicious page, or submitting a crafted form [1]. No authentication details beyond a user with certain privileges is required; the attack can be launched remotely.

Impact

Successful exploitation enables an attacker to inject arbitrary HTML and JavaScript into the victim's browser session. This could be used to perform actions such as redirecting users to malicious sites, injecting advertisements, or stealing sensitive session data [1]. The vulnerability is considered moderately dangerous and is expected to be used in mass-exploit campaigns targeting WordPress sites regardless of size or popularity [1].

Mitigation

The vendor has not yet released an official patch; however, a mitigation rule is available through Patchstack that can block attacks until an update is deployed. The recommended immediate action is to update the plugin when a patched version becomes available. If updating is not possible, users should seek assistance from their hosting provider or web developer to apply workarounds [1].
