Payload is a free and open source headless content management system. In versions before 3.90.0 and canary versions before 4.0.0-canary.34, an authenticated user who can update or delete uploads stored locally can cause file cleanup to remove unintended files outside the configured upload directory, resulting in data loss or service disruption. Deployments that restrict upload management to trusted users are less exposed. This issue is fixed in versions 3.90.0 and 4.0.0-canary.34.

GHSA-p223-2wr2-j562 — Payload: Incomplete validation during the upload file lifecycle

Affected: npm: payload

## Impact Under certain conditions, an authenticated user with permission to modify uploads could cause unintended files to be removed during file cleanup. This may result in data loss or service disruption.

You are affected if: - You use Payload upload collections with local file storage. - Untrusted authenticated users can update or delete uploads.

Deployments that restrict upload management to trusted users are less exposed.

## Patches Payload now validates uploaded filenames and ensures file cleanup remains within the configured upload directory.

Users should upgrade Payload packages to `>= 3.90.0` or `>= 4.0.0-canary.34`.

## Workarounds Restrict upload update and deletion operations to trusted users and validate submitted filenames. These measures are temporary mitigations. Upgrading to a patched version is recommended.
