CVE-2024-27100
Discourse is an open source platform for community discussion. In affected versions the endpoints for suspending users, silencing users and exporting CSV files weren't enforcing limits on the sizes of the parameters that they accept. This could lead to excessive resource consumption which could render an instance inoperable. A site could be disrupted by either a malicious moderator on the same site or a malicious staff member on another site in the same multisite cluster. This issue is patched in the latest stable, beta and tests-passed versions of Discourse. Users are advised to upgrade. There are no known workarounds for this vulnerability.

En las versiones afectadas, los endpoints para suspender usuarios, silenciar usuarios y exportar archivos CSV no imponían límites en los tamaños de los parámetros que aceptaban. Esto podría provocar un consumo excesivo de recursos que podría dejar una instancia inoperable. Un sitio podría verse interrumpido por un moderador malintencionado en el mismo sitio o por un miembro del personal malicioso en otro sitio en el mismo clúster multisitio. Este problema está solucionado en las últimas versiones estable, beta y de prueba de Discourse. Se recomienda a los usuarios que actualicen. No se conocen workarounds para esta vulnerabilidad."
