Report: CVE-2026-48810 - FreeScout: Thread Edit Authorization Bypass via Missing Mailbox Check - Full Analysis

CVE ID :CVE-2026-48810 Published : May 29, 2026, 8:16 p.m. | 45 minutes ago Description :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. Severity: 4.3 | MEDIUM Visit the link for more details, such as CVSS details, affected products, timeline, and more...
