CVE-2025-4405 is a stored cross-site scripting vulnerability in the Hot Random Image plugin for WordPress, affecting all versions up to 1.9.2. The vulnerability is due to improper neutralization of input in the 'link' parameter, allowing authenticated users with Contributor or higher privileges to inject arbitrary web scripts. These scripts execute in the context of users viewing the injected pages, potentially leading to information disclosure or session manipulation. The CVSS 3.1 vector indicates network attack vector, high attack complexity, low privileges required, no user interaction, and impacts confidentiality and integrity with no impact on availability.

An attacker with Contributor-level access or above can exploit this vulnerability to inject malicious scripts that execute in other users' browsers when they access the compromised pages. This can lead to partial confidentiality and integrity loss, such as theft of user data or session tokens. There is no indication of availability impact. The vulnerability does not appear to be exploited in the wild as of the published date.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict Contributor-level access to trusted users only and consider disabling or removing the Hot Random Image plugin if possible. Monitor for plugin updates from hotwptemplates and apply official patches promptly once available.
