CVE-2025-24808

  2. Vulnerabilities (CVE)
  3. CVE-2025-24808
Discourse is an open-source discussion platform. Prior to versions `3.3.4` on the `stable` branch and `3.4.0.beta5` on the `beta` branch, someone who is about to reach the limit of users in a group DM may send requests to add new users in parallel. The requests might all go through ignoring the limit due to a race condition. The patch in versions `3.3.4` and `3.4.0.beta5` uses the `lock` step in service to wrap part of the `add_users_to_channel` service inside a distributed lock/mutex in order to avoid the race condition.

Summary
  • (es) Discourse es una plataforma de discusión de código abierto. Antes de las versiones 3.3.4 de la rama estable y 3.4.0.beta5 de la rama beta, alguien que estuviera a punto de alcanzar el límite de usuarios en un mensaje directo grupal podía enviar solicitudes para agregar nuevos usuarios en paralelo. Debido a una condición de ejecución, todas las solicitudes podían procesarse ignorando el límite. El parche de las versiones 3.3.4 y 3.4.0.beta5 utiliza el paso de bloqueo del servicio para encapsular parte del servicio `add_users_to_channel` dentro de un bloqueo/mutex distribuido y así evitar la condición de ejecución.
