# FV Player 8 WordPress plugin: stored script injection via video field

Link for people: https://infrastack.ai/live/CVE-2026-110531 (this .md is for agents)

The FV Player 8 plugin for WordPress does not sanitize the 'fv_player_videos' parameter, so logged-in subscribers can save scripts into pages. Those scripts run in the browser of any user who opens the injected page.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed FV Player version in the WordPress plugins screen; versions up to and including `8.1.9` are affected.
- Check whether the setting "Allow visitors to upload videos to their profile" is enabled in the FV Player settings.

## Fix

- FV Player 8: a fixed version is referenced in the linked patch, but the sources here do not state it; unknown.

## Timeline

## From the sources

The FV Player 8 plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'fv_player_videos' parameter in all versions up to, and including, 8.1.9 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This requires the administrator-controlled "Allow visitors to upload videos to their profile" setting to be enabled, without which the vulnerable save routine is inaccessible to Subscriber-level users.
