Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

ProcessWire CMS (processwire/processwire, versions up to and including 3.0.246) is vulnerable to resource-exhaustion denial of service. An attacker with a low-privileged account holding the lang-edit permission can upload a crafted ZIP file through Language Support, which is extracted without size or resource limits before validation. No fixed version is listed, and the source gives few further details.
