The WP Google Street View (with 360° virtual tour) & Google maps + Local SEO WordPress plugin versions up to 1.1.3 contain a stored cross-site scripting vulnerability (CWE-79) in the 'wpgsv' shortcode. This vulnerability is due to improper neutralization of input during web page generation, specifically insufficient sanitization and escaping of user-supplied shortcode attributes. Authenticated attackers with contributor-level permissions or higher can exploit this to inject arbitrary JavaScript that executes in the context of users viewing the compromised pages. The vulnerability has a CVSS 3.1 base score of 6.4 (AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N), reflecting network attack vector, low attack complexity, and partial impact on confidentiality and integrity with no impact on availability. No patch or official remediation guidance is currently available from the vendor or other authoritative sources.

Successful exploitation allows authenticated users with contributor-level access or above to inject persistent malicious scripts into pages via the 'wpgsv' shortcode. These scripts execute in the browsers of users who visit the affected pages, potentially leading to partial confidentiality and integrity loss, such as session hijacking or unauthorized actions performed in the context of the victim user. There is no reported impact on system availability. No known active exploitation has been documented.

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 vulnerable plugin if feasible. Monitor for plugin updates from the vendor that address this vulnerability.
