Attack vector: Network
Complexity: Low
Privileges needed: None
User interaction: None
Impact: Limited impact
Weakness: CWE-79

Impact

Unauthenticated attackers can execute arbitrary JavaScript in users' browsers via stored cross-site scripting. Exploitation requires network access to the site, the 'Parse Vimeo and YouTube links' (parse_comments) setting enabled, and shortcodes using liststyle="season".

Root cause

The plugin fails to sanitize and escape the 'synopsis' shortcode attribute before rendering it into the page.

Affected systems

CVSS v3.1 · CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:L/A:N

Fix & remediation

NVD description

The FV Flowplayer Video Player plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'synopsis' Shortcode Attribute in all versions up to, and including, 7.5.54.7212 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. This requires the 'Parse Vimeo and YouTube links' (parse_comments) option to be enabled and the liststyle attribute set to "season" for the vulnerable code path to be reached.
