CVE-2026-34746
Payload has Authenticated SSRF via Upload Functionality
Description
### Impact An authenticated Server-Side Request Forgery (SSRF) vulnerability existed in the upload functionality. Authenticated users with `create` or `update` access to an upload-enabled collection could cause the server to make outbound HTTP requests to arbitrary URLs. Consumers are affected if ALL of these are true: - Payload version **< v3.79.1** - At least one collection with `upload` enabled - An authenticated user has `create` or `update` access to that collection ### Patches This vulnerability has been patched in **v3.79.1**. Users should upgrade to **v3.79.1** or later. ### Workarounds Until consumers can upgrade: - Restrict `create` and `update` access to upload-enabled collections to trusted roles only. - Limit outbound network access from your Payload server where possible.
