CVE-2026-41192

Full vulnerability record from the local CVENow database.

Description

FreeScout is a free self-hosted help desk and shared mailbox. Prior to version 1.8.215, the reply and draft flows trust client-supplied encrypted attachment IDs. Any IDs present in `attachments_all[]` but omitted from retained lists are decrypted and passed directly to `Attachment::deleteByIds()`. Because `load_attachments` returns encrypted IDs for attachments on a visible conversation, a mailbox peer can replay those IDs through `save_draft` and delete the original attachment row and file. Version 1.8.215 fixes the vulnerability.

      "value": "FreeScout es un sistema de mesa de ayuda y buzón compartido autoalojado gratuito. Antes de la versión 1.8.215, los flujos de respuesta y borrador confían en los ID de adjuntos cifrados proporcionados por el cliente. Cualquier ID presente en “attachments_all[]” pero omitido de las listas retenidas se descifra y se pasa directamente a “Attachment::deleteByIds()”. Debido a que “load_attachments” devuelve ID cifrados para adjuntos en una conversación visible, un par de buzón puede reproducir esos ID a través de “save_draft” y eliminar la fila y el archivo del adjunto original. La versión 1.8.215 corrige la vulnerabilidad."
