Published: 07/20/2026 (07/20/2026, 15:31:17 UTC)
Source: CVE Database V5
Vendor/Project: rConfig
Product: rConfig v8 Core

Description

rConfig Core before 8.2.8 contains a privilege escalation vulnerability that allows authenticated users to assign arbitrary roles to any account by submitting an unvalidated role field through the Users API during user creation or profile updates. Attackers can exploit the missing allowlist validation and absent admin-level authorization check in StoreUserRequest to mass-assign the Admin role directly to the User model, granting access to privileged features. rConfig Pro and Enterprise are not affected.

Technical Analysis

CVE-2026-63102 describes a privilege escalation vulnerability in rConfig Core before version 8.2.8. Authenticated users can exploit the lack of allowlist validation and absence of admin-level authorization checks in the StoreUserRequest component to assign arbitrary roles, including Admin, to any user account via the Users API. This enables unauthorized access to privileged features. The issue is specific to rConfig Core; Pro and Enterprise editions are unaffected.

Potential Impact

An attacker with authenticated access can escalate privileges by assigning themselves or others the Admin role, thereby gaining unauthorized access to privileged features within rConfig Core. This compromises the integrity of user role assignments and could lead to unauthorized administrative control over the system.

Mitigation Recommendations

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the Users API to trusted users only and monitor for suspicious role assignment activities. Avoid using affected versions of rConfig Core in sensitive environments if possible.
