Key Information:
What is CVE-2024-53851?
Discourse, an open-source community discussion platform, suffers from a denial of service vulnerability due to improper URL limit enforcement in its inline onebox generation feature. Authenticated users can exploit this by sending excessive URL requests, potentially leading to service disruption. This issue has been mitigated in the latest stable, beta, and tests-passed releases of Discourse. Users unable to upgrade should disable the inline onebox feature for all domains and clear the allowed inline onebox domains to safeguard against this vulnerability.
