Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to hold at minimum a WordPress subscriber-level account on the target site, as confirmed by PR:L in the CVSS vector. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 6.8 Medium score (AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:N) reflects a meaningful but conditionally exploitable vulnerability. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker registers a free subscriber account on a WordPress site with open user registration and JetFormBuilder <= 3.6.1 installed. By submitting a specially crafted form request that satisfies the specific conditions reflected by the AC:H rating - likely involving manipulated role-related form fields or endpoint parameters - the attacker triggers incorrect privilege assignment and elevates their account to an editor or administrator role. … |
| Remediation | Update JetFormBuilder to a version later than 3.6.1. … Detailed patch versions, workarounds, and compensating controls in full report. |
