Insufficient control of custom field value sizes

Published Jan 12, 2024 · Updated Jun 3, 2025 · Assigned by GitHub_M

Description

Discourse is a platform for community discussion. For fields that are client editable, limits on sizes are not imposed. This allows a malicious actor to cause a Discourse instance to use excessive disk space and also often excessive bandwidth. The issue is patched 3.1.4 and 3.2.0.beta4.
