The Workreap WordPress theme before 2.2.2 AJAX actions workreap_award_temp_file_uploader and workreap_temp_file_uploader did not perform nonce checks, or validate that the request is from a valid user in any other way. The endpoints allowed for uploading arbitrary files to the uploads/workreap-temp directory. Uploaded files were neither sanitized nor validated, allowing an unauthenticated visitor to upload executable code such as php scripts.

Several AJAX actions available in the Workreap WordPress theme before 2.2.2 lacked CSRF protections, as well as allowing insecure direct object references that were not validated. This allows an attacker to trick a logged in user to submit a POST request to the vulnerable site, potentially modifying or deleting arbitrary objects on the target site.

The Workreap WordPress theme before 2.2.2 had several AJAX actions missing authorization checks to verify that a user was authorized to perform critical operations such as modifying or deleting objects. This allowed a logged in user to modify or delete objects belonging to other users on the site.

The Workreap WordPress theme before 2.6.3 has a vulnerability with the notifications feature as it's possible to read any user's notification (employer or freelancer) as the notification ID is brute-forceable.

The Workreap WordPress theme before 2.6.4 does not verify that an addon service belongs to the user issuing the request, or indeed that it is an addon service, when processing the workreap_addons_service_remove action, allowing any user to delete any post by knowing or guessing the id.

The Workreap plugin for WordPress, used by the Workreap - Freelance Marketplace WordPress Theme, is vulnerable to authentication bypass in all versions up to, and including, 3.3.1. This is due to the plugin not properly verifying a user's identity prior to logging them in when verifying an account with an email address. This makes it possible for unauthenticated attackers to log in as registered users, including administrators, if they know user's email address. This is only exploitable fi the user's confirmation_key has not already been set by the plugin.

The Workreap plugin for WordPress, used by the Workreap - Freelance Marketplace WordPress Theme, is vulnerable to arbitrary file uploads due to missing file type validation in the 'workreap_temp_upload_to_media' function in all versions up to, and including, 3.3.2. This makes it possible for authenticated attackers, with Subscriber-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible.
