CVE-2026-41192: CWE-862: Missing Authorization in freescout-help-desk freescout
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.

Technical Summary
CVE-2026-41192 is a missing authorization vulnerability (CWE-862) in FreeScout, a self-hosted help desk software. Before version 1.8.215, the application trusts client-supplied encrypted attachment IDs in reply and draft workflows. Attachments present in the attachments_all[] array but omitted from retained lists are decrypted and passed directly to Attachment::deleteByIds(), enabling an attacker with mailbox access to replay these IDs via save_draft and delete original attachment files. This vulnerability allows unauthorized deletion of attachments within visible conversations. The vulnerability is resolved in FreeScout version 1.8.215.
Potential Impact
The vulnerability enables an attacker with at least limited mailbox access (privilege level: low) to delete attachments they should not be authorized to remove, impacting data integrity (high impact) and causing limited availability loss (low impact). There is no confidentiality impact reported. No known exploits in the wild have been documented.
Mitigation Recommendations
Upgrade FreeScout to version 1.8.215 or later, where this vulnerability is fixed. Since this is a self-hosted product, administrators must apply the update manually. Patch status is not explicitly confirmed in vendor advisories but the version 1.8.215 release notes indicate the issue is resolved. Until patched, restrict mailbox peer access to trusted users only.
