What is CVE-2023-44388?

A vulnerability in the Discourse open source platform allows a malicious request to rapidly fill production log files, potentially leading to server disk space exhaustion. This situation can disrupt service availability for users. Administrators can mitigate this issue by updating to the patched versions 3.1.1 or 3.2.0.beta2, or by temporarily reducing the 'client_max_body_size' directive in their nginx configuration to limit the size of upload requests. For detailed mitigation strategies, consult the linked resources.
