CVE-2026-42695: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in FolioVision FV Flowplayer Video Player

The FolioVision FV Flowplayer Video Player WordPress plugin (fv-wordpress-flowplayer) suffers from a stored cross-site scripting vulnerability due to improper neutralization of input during web page generation. This vulnerability affects all versions from initial releases through 7.5.54.7212. Exploitation could allow an attacker with low privileges and requiring user interaction to execute script code in the context of the victim's browser, potentially impacting confidentiality, integrity, and availability to a limited extent. The CVSS 3.1 vector is AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L, reflecting network attack vector, low attack complexity, low privileges required, user interaction required, scope changed, and low impact on confidentiality, integrity, and availability.

Successful exploitation of this stored XSS vulnerability could allow an attacker to execute arbitrary scripts in the context of users visiting affected pages, potentially leading to information disclosure, session hijacking, or other limited impacts on confidentiality, integrity, and availability. The scope is changed, meaning the vulnerability affects resources beyond the security scope of the vulnerable component. However, the impact is rated as low for confidentiality, integrity, and availability.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should consider limiting privileges of users who can submit content to the plugin and apply standard WordPress security best practices to reduce risk. Monitor vendor channels for updates and apply patches promptly once released.
