Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Insecure Temporary File: Temporary files written to disk during the deferred buffering of uploaded data could be readable by other local users on shared systems if owner-only POSIX permissions (rw-------) are not explicitly enforced.
Insecure Temporary File: The core fileupload component previously failed to adequately restrict file permissions on temporary storage directories, exposing uploaded files to unauthorized local access.
Denial of Service: Attackers can cause a remote denial of service via resource exhaustion by sending crafted multipart requests with oversized headers that exceed internal limits.
