2DescriptionCVE.org
A weakness has been identified in SourceCodester Inventory Management System 1.0. This vulnerability affects unknown code of the file /api/users_handler.php of the component User Registration Endpoint. This manipulation of the argument role causes improper access controls. Remote exploitation of the attack is possible. The exploit has been made available to the public and could be used for attacks.
AnalysisAI
Privilege escalation via role parameter manipulation in SourceCodester Inventory Management System 1.0 allows unauthenticated remote attackers to self-assign elevated roles during user registration. The vulnerability resides in /api/users_handler.php, where the application fails to enforce server-side restrictions on the role argument at the User Registration Endpoint, enabling account creation with admin-level privileges. …

Vulnerability AssessmentAI
| Exploitation | The User Registration Endpoint at /api/users_handler.php must be network-reachable without prior authentication, consistent with PR:N in the CVSS 4.0 vector. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 base score of 5.5 with vector AV:N/AC:L/AT:N/PR:N/UI:N reflects a low-complexity, unauthenticated, network-reachable attack requiring no user interaction - a favorable attack profile for an adversary. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An unauthenticated attacker sends a crafted HTTP POST request to /api/users_handler.php with the role parameter set to an elevated value such as 'admin' or an integer representing administrative privilege. The server processes the registration without validating or overriding the role assignment, creating an account with full administrative access. … |
| Remediation | No vendor-released patch has been identified at time of analysis - SourceCodester does not publish a formal security advisory or tracked release for this issue. … Detailed patch versions, workarounds, and compensating controls in full report. |
