An incorrect authorization issue allows forceful browsing when Drupal Commerce is used in conjunction with the JSON:API module. This allows users without proper permissions to access unpublished product variations. This issue specifically affects sites that maintain both published products and unpublished product variations.

The Webform Share submodule, which allows site builders to expose webforms for embedding on other sites, contains a flaw where submissions for Ajax-enabled webforms can bypass anti-spam protections. This occurs when the webform relies on compatible Form-API-based anti-spam protections, such as Honeypot or Antibot. Approximately 436,400 instances of Drupal were identified globally as potentially exposed.

The Media module supports oEmbed, which utilizes two discovery mechanisms: `providers.json` and URL discovery. The URL discovery code can be exploited to trick the system into making unauthorized server-side requests to any arbitrary URL. This is a Server-Side Request Forgery (SSRF), a flaw where an attacker can force a server to send requests to an unintended location.

The issue allows an access bypass, where private files uploaded by an anonymous user are visible to all anonymous users, rather than just the user who uploaded them. This occurs on sites that allow anonymous users to upload files into a private file system.
