OpenSupports 4.11.0 — SQL Injection

The endpoint POST /api/staff/get-new-tickets concatenates the user-controlled parameter departmentId directly into the SQL WHERE clause without parameter binding. As a result, an authenticated staff user (level ≥ 1) can inject SQL to alter the filter logic, effectively bypassing department scoping and disclosing tickets beyond their intended access.This issue affects OpenSupports: 4.11.0.

OpenSupports 4.11.0 — SSRF via test imap and smtp endpoints

Two unauthenticated diagnostic endpoints allow arbitrary backend-initiated network connections to an attacker‑supplied destination. Both endpoints are exposed with permission => 'any', enabling unauthenticated SSRF for internal network scanning and service interaction. This issue affects OpenSupports: 4.11.0.

OpenSupports 4.11.0 — Insecure Direct Object Reference in supervised list

OpenSupports exposes an endpoint that allows the list of 'supervised users' for any account to be edited, but it does not validate whether the actor is the owner of that list. A Level 1 staff member can modify the supervision relationship of a third party (the target user), who can then view the tickets of the added 'supervised' users. This breaks the authorization model and filters the content of other users' tickets.This issue affects OpenSupports: 4.11.0.

OpenSupports v4.11.0 is vulnerable to Unrestricted Upload of File with Dangerous Type. In the comment function, an attacker can bypass security restrictions and upload a .bat file by manipulating the file's magic bytes to masquerade as an allowed type. This can enable the attacker to execute arbitrary code or establish a reverse shell, leading to unauthorized file writes or control over the victim's station via a crafted file upload operation.
