Author-level access is needed to plant the block (PR:L) but the leaked token then discloses data to unauthenticated visitors, crossing a trust boundary (S:C); confidentiality-only impact.

DescriptionCVE.org

Ninja Forms WordPress plugin version 3.14.8 and prior contains a missing authorization vulnerability in the render callback of the ninja-forms/submissions-table Gutenberg block that allows authenticated attackers with Author-level privileges to expose stored form submissions to unauthenticated visitors by embedding the block with an arbitrary formID on a published post. Attackers can retrieve the signed bearer token injected into every page visitor's browser via wp_localize_script and use it against the REST API submissions endpoint to access all saved form submission field values, including sensitive personally identifiable information such as names, email addresses, and phone numbers.

AnalysisAI

Broken authorization in the Ninja Forms WordPress plugin (versions 3.14.8 and prior) lets an authenticated Author-level user expose stored form submissions to any unauthenticated site visitor by embedding the ninja-forms/submissions-table Gutenberg block with an arbitrary formID on a published post. Because the block's render callback performs no capability check and injects a signed bearer token into every visitor's browser via wp_localize_script, anyone loading the page can replay that token against the REST submissions endpoint and read all saved field values, including PII such as names, emails, and phone numbers. …

Vulnerability AssessmentAI

Exploitation Exploitation requires an authenticated WordPress account with at least Author-level privileges to embed the `ninja-forms/submissions-table` Gutenberg block, and the site must run the block editor with Ninja Forms 3.14.8 or earlier and have stored submissions for the targeted formID. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The supplied CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N, base 7.1) captures the shape well: network reachable, low complexity, no user interaction, but requiring low privileges (PR:L) to plant the block, with high confidentiality impact and no integrity or availability impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker who holds or has phished an Author-level WordPress account publishes an innocuous-looking post containing the `ninja-forms/submissions-table` block set to the formID of a sensitive contact or registration form. When any unauthenticated visitor loads that public post, their browser receives the signed bearer token via `wp_localize_script`; the attacker (or an automated scraper) reads that token from the page source and replays it against the REST submissions endpoint to exfiltrate every stored submission's field values, including names, emails, and phone numbers. …
Remediation Patch available per vendor advisory - upgrade Ninja Forms to the fixed release above 3.14.8; consult the plugin changelog at https://wordpress.org/plugins/ninja-forms/changelog/ for the exact patched version (the input does not name a specific fix version, so verify it there before deploying) and review the VulnCheck advisory at https://www.vulncheck.com/advisories/ninja-forms-missing-authorization-in-submissions-table-gutenberg-block-discloses-form-submissions-to-unauthenticated-visitors. … Detailed patch versions, workarounds, and compensating controls in full report.
