# CVE-2026-41192: FreeScout's client-controlled attachment IDs allow deletion of existing conversation attachments

- Severity: CVSS 7.1 (High), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:L
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial

- Fixed in: 1.8.215

## Affected

- freescout-help-desk freescout: fixed in 1.8.215

## 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.
