Vulnerability AssessmentAI
| Exploitation | Exploitation requires a valid WordPress account with at minimum contributor-level role on the target site - anonymous or unauthenticated access is insufficient. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The NVD-reported CVSS vector (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:H/A:H) contains a notable inconsistency: PR:H implies administrator-level privilege, yet the description explicitly states contributor-level access suffices - contributors sit at PR:L in the WordPress privilege hierarchy. … 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 | Update the Eventin plugin to version 4.1.21 or later; this is the vendor-released fix confirmed by the WPScan advisory (https://wpscan.com/vulnerability/10762bf3-9663-40dc-9794-88ec7aa5b048/) and EUVD-2026-62261. … Detailed patch versions, workarounds, and compensating controls in full report. |
