Affected versions of this package are vulnerable to External Control of File Name or Path via the deleteAssociatedFiles function in packages/payload/src/uploads/deleteAssociatedFiles.ts, where a filename stored in an upload document is not validated before being resolved into a file path for deletion. An authenticated attacker with upload permissions can supply a path-traversal sequence (e.g. ../../sensitive-file) as the filename, causing the server to delete arbitrary files outside the configured static upload directory.
