Lifecycle Timeline
3DescriptionCVE.org
The Nimble Page Builder WordPress plugin through 3.3.8 does not perform an authorization check when returning page-builder content through an authenticated AJAX action, allowing any authenticated user (Subscriber+) to disclose the page-builder content of arbitrary non-public (draft, pending, private, scheduled) posts and pages.
AnalysisAI
Missing authorization in the Nimble Page Builder WordPress plugin through 3.3.8 lets an authenticated user with only Subscriber-level access read the page-builder content of arbitrary non-public posts and pages, including drafts, pending, private and scheduled items. The plugin's authenticated AJAX action returns stored page-builder content without verifying that the requester is allowed to edit the target post, so an attacker can enumerate post IDs and exfiltrate unpublished content; publicly available exploit code exists and the WPScan disclosure serves as the entry point, though the issue has not been reported as actively exploited in CISA KEV. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Requires an authenticated WordPress account of at least Subscriber level on a site running Nimble Page Builder ≤3.3.8; sites permitting open user registration effectively lower this to any remote attacker. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine but low-severity issue: a moderate priority at most. … 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, so the primary mitigation is to remove the attack surface: deactivate and, if feasible, uninstall Nimble Page Builder until an updated release appears, accepting that pages and posts built with the plugin may lose their designed layout. … Detailed patch versions, workarounds, and compensating controls in full report. |
