New in Payload: Hardening Uploads, Copy/Paste, and MCP Defaults

New in Payload: Release v3.88.0
New in Payload: Release v3.88.0

Payload 3.88.0 hardens multipart upload parsing, stops clipboard data from leaking across rows, and tightens access-control defaults for the MCP plugin's API keys.

Highlights

This release focuses on hardening — closing a multipart parsing edge case, stopping clipboard data from leaking between rows, and tightening access-control defaults for the MCP plugin — alongside a Next.js bump in our templates.


Also in this release:

  • Uploads: multipart content-type parsing no longer backtracks, closing a potential denial-of-service vector
  • Admin UI: clipboard prefix matching is tighter, preventing sibling row data from leaking during copy/paste
  • MCP plugin: the API keys collection now ships with safer access-control defaults
  • Templates: Next.js is bumped to 16.3.0

As always, you can review the complete changelog on GitHub.
