Summary

The All-in-One Video Gallery plugin for WordPress is affected in all versions up to and including 4.9.7. Its save handler does not sanitize or escape the embedcode custom field, which allows cross-site scripting (CWE-79). An authenticated attacker with Subscriber access or higher can store arbitrary web scripts that run in a user's browser when that user opens an affected page.

Description from the CNA

The All-in-One Video Gallery – Video Player & Galleries for YouTube, Vimeo & Self-Hosted Videos plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'custom_fields[embedcode]' parameter in all versions up to, and including, 4.9.7 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. The sanitization bypass is possible because the save_meta_data() handler returns early when $_POST['post_type'] is absent — a condition always true during XML-RPC requests — and the plugin unconditionally grants Subscribers the publish_aiovg_videos capability, making this exploitable by any authenticated user via a single wp.newPost XML-RPC call.
