    Payload: Uploaded XML files could execute same-origin JavaScript

    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, local upload configurations that accept XML files can store an XML file and stylesheet that execute JavaScript in the Payload origin when a logged-in user opens the file. This issue is fixed in versions 3.90.0 and 4.0.0-canary.34.

    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 unauthenticated attacker who knows an account email address or username can abuse the account lockout mechanism of a local-authentication collection to prevent that account from signing in. This issue is fixed in versions 3.90.0 and 4.0.0-canary.34.

    Payload: Incomplete validation during the upload file lifecycle

    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.

    Payload authentication token field handling issue

    Payload is a free and open source headless content management system.

    Payload external upload trust validation issue

    Payload is a free and open source headless content management system. In versions after 3.0.0 and before 3.90.0, authenticated external URL-based upload retrieval can forward authentication data to a redirected destination that was not verified as trusted, potentially exposing a valid session to an unintended recipient.
