CVE-2026-55078 Â (opens in a new tab)How to fix?

Overview
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling in the CreateTarFromZip process. An attacker can exhaust system memory and cause a service outage by uploading a zip file containing many highly compressible entries, resulting in excessive decompressed output that overwhelms the in-memory buffer. This is only exploitable if the attacker has authenticated file-upload access.
Workaround
This vulnerability can be mitigated by restricting file-upload permissions to trusted users or placing a reverse proxy with request-body size limits in front of the affected service.
