Technical details

A Stored Cross-Site Scripting (XSS) vulnerability exists in the Themefic Hydra Booking plugin for WordPress (versions up to and including 1.1.44). The flaw stems from improper neutralization of user-supplied input during web page generation, allowing unauthenticated attackers to inject arbitrary web scripts. While the attack is unauthenticated, successful exploitation requires user interaction, such as a privileged user visiting a crafted page where the malicious payload is stored. Once executed, the script runs within the context of the victim's session, which can lead to session hijacking or unauthorized administrative actions. The issue is resolved in version 1.1.45.
