Vulnerability AssessmentAI
| Exploitation | Exploitation requires only that the vulnerable Advanced Customized Prompts plugin (≤1.0.1) be installed and active on a network-reachable WordPress site, and that the attacker knows or guesses a valid registered email address (administrator emails are frequently exposed via author archives, REST API /wp-json/wp/v2/users, or page footers); the account-creation path needs no pre-existing email at all. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine high-priority issue, not an inflated CVSS number. … 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 patched version is identified in the available data ('through 1.0.1' is the affected range with no stated fixed release), so treat this as: no vendor-released patch identified at time of analysis - verify directly with the plugin author for a version newer than 1.0.1. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: immediately deactivate and remove the Advanced Customized Prompts plugin from all WordPress installations, reset all administrator and user account passwords, and audit user roles for unauthorized privilege escalation. …
