The WP VR – 360 Panorama and Free Virtual Tour Builder For WordPress plugin suffers from a stored cross-site scripting vulnerability (CWE-79) due to improper neutralization of input during web page generation. Specifically, the 'hotspot-hover' parameter is not properly sanitized or escaped, allowing authenticated users with Contributor-level permissions or higher to inject malicious scripts. These scripts execute in the context of users viewing the compromised pages, potentially leading to session hijacking or other script-based attacks. The vulnerability affects all versions up to 8.5.32. The CVSS 3.1 base score is 6.4, reflecting network attack vector, low attack complexity, required privileges at the contributor level, no user interaction, and impacts on confidentiality and integrity with no availability impact. No patch or official fix information is currently available.

An authenticated attacker with Contributor-level access or higher can inject persistent malicious scripts via the 'hotspot-hover' parameter. These scripts execute in the browsers of users who view the infected pages, potentially compromising user sessions or data confidentiality and integrity. The vulnerability does not affect availability. There are no known exploits in the wild at this time.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, site administrators should restrict Contributor-level access carefully and consider removing or limiting use of the vulnerable plugin. Monitoring for suspicious activity related to injected scripts is advisable. Avoid granting unnecessary privileges to users to reduce risk.
