jshERP through 3.6 fails to validate caller permissions in role management endpoints, allowing authenticated users to modify any role's data scope or delete roles. Attackers can exploit the /role/update and /role/delete endpoints to escalate privileges, change data visibility to all data, and access all business records in the tenant.

AnalysisAI
Privilege escalation in jshERP through 3.6 lets any authenticated user - including one holding only a low-privileged tenant account (CVSS PR:L, no administrative rights, user interaction, or non-default configuration required) - modify or delete arbitrary role definitions through the /role/update and /role/delete endpoints in RoleController, which perform no caller-permission checks. Successful abuse allows an attacker to widen a role's data scope to 'all data', delete roles, and consequently read every business record in the tenant. …

Vulnerability AssessmentAI
| Exploitation | Requires a valid authenticated jshERP account of any privilege level (PR:L); no administrative rights, user interaction, or non-default configuration are needed. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine, actionable priority within its (limited) install base. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No vendor-released patch identified at time of analysis: jshERP versions through 3.6 remain affected and no fixed release is referenced in the available advisories or repository data. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory every jshERP deployment through version 3.6 and determine which are internet-facing; restrict access to trusted networks and block or tightly control /role/update and /role/delete at the reverse proxy or WAF unless explicitly required; review recent role changes and access logs for unauthorized modifications. …
