Summary
The FV Flowplayer Video Player plugin for WordPress is vulnerable to Stored Cross-Site Scripting (XSS) via comment text in all versions up to and including 7.5.49.7212 due to insufficient input sanitization and output escaping. Attackers can inject arbitrary web scripts that will execute whenever a user accesses an injected page.
Risk Assessment
This vulnerability poses a risk of injecting malicious code, which could lead to user data theft or session hijacking. However, it requires the administrator to enable the non-default 'Parse Vimeo and YouTube links' option and for a comment to be approved before it is publicly delivered.
Recommendation
It is recommended to update the plugin to the latest version and disable the 'Parse Vimeo and YouTube links' option to minimize risk. Additionally, regularly monitor and approve comments to prevent the injection of malicious code.
Original NVD description (English source)
The FV Flowplayer Video Player plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the comment text in all versions up to, and including, 7.5.49.7212 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Exploitation requires an administrator to have enabled the non-default 'Parse Vimeo and YouTube links' (parse_comments) plugin setting, and requires a submitted comment to be approved by an administrator before the payload is publicly delivered.
