3DescriptionCVE.org
yshop-crm through 2.1.3 fails to enforce authorization on the saveRedisSet and getRedisSet endpoints in CrmCustomerController, allowing any authenticated back-office user to read and modify installation-wide lead-allocation and customer auto-recycling policy. Attackers can invoke these endpoints to manipulate shared Redis keys controlling customer auto-recycling behavior, causing mass customer data deletion, disabling lead recycling, or blocking customer creation across the deployment.
AnalysisAI
Missing authorization in yshop-crm through 2.1.3 lets any authenticated back-office user, regardless of role or privilege level, invoke the saveRedisSet and getRedisSet endpoints in CrmCustomerController and rewrite the installation-wide Redis keys that drive lead allocation and customer auto-recycling. Because the scheduled CustomerAutoJob consumes those same keys, a low-privilege staff account can disable recycling, block customer creation, or trigger mass customer deletion across the deployment; publicly available exploit code exists (the VulnCheck-referenced CVE request PoC on GitHub), while no active exploitation has been confirmed and the CVE is not listed in CISA KEV. …

Vulnerability AssessmentAI
| Exploitation | Requires a valid authenticated back-office (admin-panel) user account of any privilege level - the saveRedisSet and getRedisSet endpoints in CrmCustomerController perform no authorization/role check (CWE-862), so any logged-in staff user can invoke them. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine but bounded-priority issue. … 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: the supplied references are source-code pointers and a VulnCheck advisory rather than a fixed release, and yshop-crm 2.1.3 is the latest version referenced. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all yshop-crm instances through 2.1.3, confirm exposure of the CrmCustomerController saveRedisSet and getRedisSet endpoints, restrict those endpoints to trusted administrative roles only, disable or review unnecessary back-office accounts, and monitor Redis key changes and CustomerAutoJob activity for unauthorized lead-allocation or recycling changes. …
