AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Unauthenticated network REST routes with no nonce (AV:N/AC:L/PR:N/UI:N); unauth plugin install and file write give full C/I/A impact independent of the conditional uploads-PHP RCE.

The AI Website Builder WordPress plugin (GitHub build) 1.0.0 does not perform any authorisation or nonce check on its REST API routes, allowing unauthenticated attackers to install and activate plugins and themes, import content from a URL under their control, write a file of their choosing into the uploads directory, and delete site content and media. On a host that serves PHP from the uploads directory, that file write is remote code execution.

AnalysisAI
Remote code execution and full site takeover affect the AI Website Builder WordPress plugin (GitHub build 1.0.0), whose REST API routes perform no authorisation or nonce validation. Unauthenticated attackers can install and activate arbitrary plugins and themes, import content from a URL they control, write an arbitrary file into wp-content/uploads, and delete site content and media - any of the code-installation paths yields RCE, and the arbitrary uploads file write is directly RCE on hosts that serve PHP from the uploads directory. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | No authentication, user interaction, or special privileges are required - the CVSS vector is AV:N/AC:L/PR:N/UI:N and the description confirms the REST routes lack any authorisation or nonce check, so exploitation works remotely against default configurations of the AI Website Builder plugin (GitHub build 1.0.0). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The supplied CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, 9.8) is well supported by the description: the attack is remote, requires no authentication, no user interaction, and low complexity, and the impact spans confidentiality (content import/read paths), integrity (arbitrary plugin/theme install, file write, content deletion), and availability (media/content deletion). … 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 version is identified in the available data. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: immediately deactivate and delete the AI Website Builder plugin from all WordPress installations, check admin audit logs for suspicious activity dating back to plugin installation, and review active themes and plugins for unauthorized additions. …
