5DescriptionCVE.org
yshop-crm through 2.1.3 contains a missing authorization vulnerability in the StoreProductController onSale handler that allows authenticated back-office users to modify product sale status. Attackers can invoke the GET /admin-api/product/store-product/sale endpoint with sequential product IDs to withdraw entire product catalogs from sale or re-enable withdrawn products without proper permission checks.
AnalysisAI
Missing authorization in the StoreProductController onSale handler of Yshop CRM through 2.1.3 allows any authenticated back-office user (regardless of assigned role) to toggle product sale status by calling GET /admin-api/product/store-product/sale with sequential product IDs, letting them withdraw entire catalogs from sale or re-enable withdrawn products. The flaw is an integrity-only issue (CVSS 3.1 base 5.3, PR:L) - it is not reachable anonymously and causes no data disclosure or service outage. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid authenticated back-office (admin-api) account with low privileges (PR:L) - it is NOT remotely exploitable by an anonymous attacker. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuinely low-to-moderate risk issue despite the CRITICAL-sounding CWE-862 label. … 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 is identified in the available data, and no fixed version number is provided, so operators should plan for a code-level fix: add the missing permission/authorization annotation (for example a Spring Security @PreAuthorize permission check such as the product-status permission used elsewhere in the module) to the StoreProductController onSale handler and to the StoreProductServiceImpl toggle method at line 552, then rebuild and redeploy the yshop-module-product-biz module. … Detailed patch versions, workarounds, and compensating controls in full report. |
