How the CVE Works:
CVE-2025-26917 is a critical vulnerability in the HasThemes WP Templata plugin for WordPress, affecting versions up to 1.0.7. The flaw arises from improper neutralization of user-supplied input during web page generation, leading to Reflected Cross-site Scripting (XSS). Attackers can exploit this by injecting malicious scripts into web pages viewed by other users. When a victim interacts with the compromised page, the script executes in their browser, potentially stealing sensitive information, hijacking sessions, or performing actions on behalf of the user. The vulnerability is particularly dangerous because it requires minimal user interaction and can be exploited remotely.
