Overview
CVE-2025-50849 is a severe security vulnerability affecting CS Cart 4.18.3, a popular e-commerce software. This vulnerability is an instance of Insecure Direct Object Reference (IDOR), a widespread security flaw where an application exposes a reference to an internal implementation object. In this case, the user profile functionality in CS Cart allows an authenticated user to manipulate and control the sticker setting of other users’ accounts. This vulnerability, if exploited, can lead to a serious system compromise or data leakage, thereby posing a significant risk to any business utilizing CS Cart 4.18.3.

CS Cart | 4.18.3
How the Exploit Works
The vulnerability lies in the user profile functionality of CS Cart 4.18.3. It enables or disables stickers through a parameter (company_id) sent in the request. However, this operation is not adequately validated on the server side. Therefore, an authenticated user can manipulate the request to target other users’ accounts and toggle the sticker setting by modifying the company_id or other object identifiers.
Conceptual Example Code
Here’s a conceptual example of how the vulnerability might be exploited, using an HTTP request:
POST /user_profile/sticker_setting HTTP/1.1
Host: target.example.com
Content-Type: application/json
Authorization: Bearer [Authenticated User's Token]
{ "company_id": "[Victim's company_id]", "sticker_setting": "enabled" }In this example, an attacker modifies the ‘company_id’ in the request body to the company_id of the victim. The server then processes the request, enabling or disabling the sticker settings for the victim’s account without proper validation.
Mitigation Guidance
To mitigate this vulnerability, users are urged to apply the vendor patch as soon as it becomes available. Until then, using Web Application Firewalls (WAFs) or Intrusion Detection Systems (IDS) can provide temporary mitigation by detecting abnormal request patterns and blocking potentially malicious requests.
