Media Cloud for Amazon S3, Imgix, Google Cloud Storage, DigitalOcean Spaces and more < 4.5.25 - Authenticated (Contributor+) Stored Cross-Site Scripting via Shortcode

Description The Media Cloud for Bunny CDN, Amazon S3, Cloudflare R2, Google Cloud Storage, DigitalOcean and more plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin’s shortcode in all versions up to, and including, 4.5.24 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
