CVE-2026-48810: CWE-285: Improper Authorization in freescout-help-desk freescout
FreeScout is a free help desk and shared inbox built with PHP's Laravel framework. Prior to 1.8.221, while investigating the ThreadPolicy::delete issue reported previously, the same missing mailbox membership check was found in the sibling ThreadPolicy::edit method. A user with the PERM_EDIT_CONVERSATIONS permission who created a message or internal note in Mailbox A can rewrite that thread's body after an administrator removes them from Mailbox A, because the policy checks only authorship and a global permission flag — not current mailbox membership. This vulnerability is fixed in 1.8.221.
AI Analysis
Technical Summary
FreeScout, a PHP Laravel-based help desk application, had an authorization flaw in its ThreadPolicy::edit method before version 1.8.221. Users with PERM_EDIT_CONVERSATIONS permission who authored messages or notes in a mailbox could continue editing those threads after removal from that mailbox due to missing mailbox membership checks. The policy incorrectly relied on authorship and a global permission flag without verifying current mailbox membership. This vulnerability is classified under CWE-285 (Improper Authorization) and was addressed in FreeScout 1.8.221.
Potential Impact
An attacker with edit permissions and prior authorship in a mailbox can modify thread content after being removed from that mailbox, potentially leading to unauthorized alteration of conversation data. There is no impact on confidentiality or availability reported, only integrity is affected. No known exploits in the wild have been reported.
Mitigation Recommendations
This vulnerability is fixed in FreeScout version 1.8.221. Users should upgrade to version 1.8.221 or later to remediate this issue. Since no official remediation level or patch links are provided beyond this version update, verifying the upgrade from the vendor's official source is recommended. No additional mitigation steps are indicated.
