mall4j through 4.0 fails to implement authentication controls on the DELETE /prodComm endpoint in ProdCommController. Unauthenticated attackers can delete arbitrary product reviews by supplying the prodCommId parameter without authorization checks.
AnalysisAI
Unauthenticated attackers can delete arbitrary product reviews in mall4j through 4.0 by sending DELETE requests to the /prodComm endpoint in ProdCommController, which applies no authentication or authorization checks to the prodCommId parameter (CWE-306). Publicly available exploit code exists, and no credentials or user interaction are required; the only prerequisite is knowing or enumerating a valid review ID. …

Vulnerability AssessmentAI
| Exploitation | No special conditions - remote unauthenticated exploitation against default configurations of mall4j (through 4.0) where the yami-shop-api DELETE /prodComm endpoint is network-reachable. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a real but LOW-severity issue best described as an unauthenticated data-tampering flaw rather than a high-impact break. … 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 was identified at time of analysis; the available GitHub references point to the vulnerable source code and a public proof-of-concept rather than a fixed release. … Detailed patch versions, workarounds, and compensating controls in full report. |
