Vulnerability AssessmentAI
| Exploitation | The /api/articles REST API endpoint must be network-accessible - this is the default posture for any internet-exposed Feehi CMS deployment. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 6.9 (Medium) captures a network-accessible, zero-prerequisite flaw with constrained per-access impact (VC:L/VI:L/VA:L). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | A remote unauthenticated attacker sends a crafted HTTP GET or POST request directly to the /api/articles endpoint of an internet-exposed Feehi CMS instance, receiving or manipulating article data without any credential challenge. A public POC is available via GitHub issue #87, reducing the required skill level to near-zero. … |
| Remediation | No vendor-released patch has been identified at time of analysis - the project was notified via issue report (https://github.com/liufee/cms/issues/87) but has not responded. … Detailed patch versions, workarounds, and compensating controls in full report. |
