AI Analysis
Technical Summary
CVE-2026-94494 is an authorization bypass vulnerability in jshERP through version 3.6. Authenticated users can exploit this flaw by manipulating a user-controlled key parameter in the GET /tenant/info API endpoint to enumerate and access records belonging to other tenants. This breaks tenant isolation and exposes sensitive tenant metadata including login names, validity periods, user quotas, and enabled status. The vulnerability is classified under CWE-639 (Authorization Bypass Through User-Controlled Key).
Potential Impact
The vulnerability allows authenticated users to bypass tenant isolation controls and read sensitive information of other tenants on the platform. This exposure includes login names, validity dates, user quotas, and enabled state, potentially leading to privacy violations and unauthorized data disclosure. There is no indication of data modification or denial of service impact.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official fix or patch links are provided, users should monitor vendor communications for updates. Until a fix is available, restrict access to authenticated users and consider additional access controls or API request filtering to limit key parameter manipulation.
